Will the other Senshi ever fall in love?

I always thought that love was impossible for them, since they can't afford to have such liability.
I think unless their lover also is a "moon people" than love would interfere with their duty.
That said I do ship Minako and Rei, so idk.

So Serenity had allowed her duty to be interfered by falling in love w/ an earthling?

There aren't enough men with Ferraris for every girl out there, sadly. And neither Naoko nor her characters will ever settle down for anything less.

^Poor Naru. She was close to getting a rich guy with a Ferrari. Then she had to settle for less.

The senshi only experienced love once and that was during the time of the Silver Millennium when they met the four generals.

Whether you agree or disagree with the pairings, the last chapter of Sailor V shows us Kunzite and Venus staring at each other romantically while Damburite is struggling with feelings of jealousy—because he loved Venus.

Damburite himself confirmed to Venus that she would never find love.

I am not a manga purist, but I view the manga & Crystal as the original sources.

I go by 90s : Rei has Yuichiro - Ami has Ryo Urawa - Minako had Alan but of course that didn't work out but her beauty would attract many suiters [ I never said it would be successful though]

and Mako is ever searching for someone who resembles the senior who broke her heart [but treating love in this way is a bad idea can't go around comparing every dude to the senior he moved on so should she]

Haruka and Michiru have each other and Setsuna has to guard the time door but she deserves to love instead of looking at chiba longingly from afar

Hotaru some ship her with chibiusa but that's whatever to me Hotaru is too young to be thinking about romance
Chibiusa has her choice of Pegasus and Peruru [and I like Peruru better, fight me]

I do not do that senshi x shittenou mess I hate that ship
I don't ship em with starlights either, heck outta here with that

Never liked it myself even before Crystal. Though it was a bad idea on Crystal not expanding on it. A complete missed opportunity especially when it was popular for manga fans.

She did have a kinda crush toward that (male) athlete in the anime.

that true and it was cute

They will find love. Right, now they are just young girls trying to find themselves and experience life. I mean aside for them finding love for Usagi, I think they will find a hubby (or wifey) in the future.

Rei seems like she's fine without finding love though.

I think Mako will grow out of her senior heartbreaking thing. After, all she's still a young girl.

She'd still mention her sempai to her hubby from time to time - to the annoyance of the latter, of course.

Usagi always insists that the girls live their dream. Because one day, she knows, that their mission as a warrior will have to come before everything.
Ultimately, they will never have a love life no matter what. Their love is for the princess.

You can see the senshi in Crystal Tokyo and they have no husbands.

We might not know that for certain. They could have been still dating or had lovers not shown. The idea of the Senshi devoting thier entire existence to someone else like robots is definitely not what Usagi wanted. The Sailor Warriors can still find love and fight for their princess. Haruka and Michiru do. On top of that, they don't battle enemies 24/7.

I believe Mako would find love and probably Ami too eventually.

That is speculation from your part.

No official source has ever depicted the senshi with official significant others—the exception is Michiru and Haruka.

Yes, but the possibility exists. Sailor Moon concluded when they were just 16. They will live for many years after that and will develop love for others just like they did throughout the series leading up until that point.

Also in PGSM, Motoki catches the bouquet and later proposed to Mako. That show had some heavy involvement from Ms.
Naoko. I think it's safe to assume that some of them will find love in one way or another and Naoko didn't intend for them just to be solitary drones dedicated to Usagi until death. The story just focused mostly on Usagi's love life upfront and not theirs.

The same thing for Parallel Sailor Moon where they are all married with kids.

Though these two instances are not from the main Sailor Moon anime, they are still apart of the Sailor Moon lore and show it's indeed possible for the Senshi to capture love.

And that story is written by Takeuchi herself.

It depends which continuity you're talking about.

90's anime and PGSM I believe they have the best chances at finding love as some even get their own official love interests (Ryo & Yuuichiro for Ami and Rei respectively in the 90's, and Motoki for Mako in PGSM. PGSM is also the version where the Reinako ship is closest to officially sailing, Ami and Mako also seemed like they could've had something going on in the 90's.) and there's nothing in those two versions which state that protecting the Princess comes before all else.

Manga is a different story...

Ami: Shown to have a slight crush on Motoki in the DK arc but nothing comes of it and then she's shown to be completely disinterested in romance altogether so I'm honestly not sure for her.
Rei: Had a brief infatuation with her father's assistant, but after getting her heart broken swears off men entirely and now seems to be happy finding her life's calling with her fellow Senshi. Was said to have taken a vow of Chastity in the past for Princess Serenity too. Honestly I can't really see her with anyone in the manga besides Minako, and even then I'm not sure
Mako: Perhaps her and Asanuma could work out?
Minako: The whole point of her plotline is that she'll always ultimately choose Duty and her Princess over love, I don't believe Ace was so much cursing Minako here rather than just revealing a very poignant truth. That's the real tragic irony here, despite being the Goddess of Love it seems Venus is destined to never find romantic love for herself. As much as I ship Minako with others like Kunzite, Rei and Usagi in particular, I have to admit that I adore this concept. Personally I could easily see Manga!Minako as being Aromantic, as even Artemis could tell that she was never truly serious about any of her "1000 first loves" even before she awakened with her memories, and by the Stars arc it seems she's happily come to terms with this fact with the whole "We don't need men" scene with Rei. I think she'll continue to have casual flings here and there, (cause while I believe she's Aro I don't think she's also Ace) but the most serious she'll ever get with someone is maybe entering into some kind of Plasi queerplatonic relationship with Rei. I think in this respect her and Rei make a good match since they'd both agree that their duty as Senshi and devotion to their Princess comes before anything, even each other. I'm sure Haruka and Michiru have a similar understanding and that's also why they were able to work out.
Setsuna: Will continue to hopelessly pine after Endymion, Or if not perhaps entering into a polyamorous OT3 with Haruka and Michiru? (They are pretty much all married already in the manga) Her and Beryl could also make a potentially interesting pair but that's more Musical Territory.
Hotaru: Has Chibi-Usa. I think besides maybe Reinako she has the best chance out of the rest of the Senshi of getting into a relationship in the future, yes Chibi-Usa has Helios but she also has two hands.

I don't think Serenity cared tbh

To be fair, Umino has every opportunity to become the next Steve Irwing or Bill Gates (more likely for the CNSV Amano version tho) so thats not really less. Just a delayed satisfaction.
