Because I'm lazy I'm just throwing everyone on one thing, but safe to say all my guys 'cept Omega are available for escorting/helping people get to places they need to. Right off the back, Celty and Felwinter will likely be the most capable, given the former already has a scythe (her trademark weapon thanks Shinra and the latter has space magic. ...well, Cayde has knives and bombs so there's that. Technically he didn't bring them if they were already stashed on the ship, right? Right. Cal will be better help once he's got his lightsabers, but he can still use the Force to push through things too. Marc wishes he could've kept that shovel on 'em.

AS FOR THE REST OF THINGS...

Felwinter knows some pertinent things once he realizes they may be pertinent anyway. Just sayin'.
