This is literally the weapon of Coco Adel from RWBY

COCO ADEL / VELVET

"Huh, just like he said." Ruby said, watching as Crescent Rose lap honey from an open jar next to Jaune.

"Why are they always drawn to that buffoon?" Weiss huffed as Myrtenaster was curled into Jaune's chest.

"It must be a natural charm of his." Blake pondered aloud, Gambol's Shroud in his lap.

Yang chuckled. "You mean like his animal magnetism?" Yang finger-gunned as everyone else groaned, watching Ember and Celica rest their heads on his thighs.

"Could he at least call me when Anesidora is here with him?!" Velvet whined, watching as a second Jaune played footsie with the original.

"Come on, Velv," Coco hung an arm around her friend's shoulder, "At least they're having fun. I haven't seen Gianduja so happy!" Said Rhyperior was sitting on Anesidora's lap.

Ok while I am wanting to keep the Main 8's weapons only as humans, so this'll be a one off that's sorta kinda non-canon.

Also, don't know any of those so here's my interpretation with some of yours man, apologies in advance (and for how late this ask was ^^;).

Weeks had gone by since the RWBYJNPR Living Weapons incident, and by the arguably genius or completely idiotic choice of one Coco Adel so did she follow their footsteps. From the Dust concoction rose their weapons, now mechanical humanoids.

Gianduja became something akin to an Italian mobster, getup and all, yet with a New Orleans accent. Acting as a sort of bodyguard to the fashonista but also her closest friend, with his robotic arms equipped with triangular gold studs and rotary cylinders for wrists to make his fingers engage their gatling gun function.

Velvet's unique camera transformed into a young woman about her height, dressed a steampunk scientist. Anesidora wears her camera on her head like a VR set, able to utilize what she's seen from her memory but she is a mite forgetful so she'll view her pictures to help her remember.

Sharp Retribution is much like how people perceived Fox himself at first glance, quiet and keeps to herself. All of Beacon knows to give her a wide berth since...well she can't sheath her arm sized blades! However she found good company with Gianduja who does more than enough to get Sharp out of her shell.
