If you want an Arena squad, Selena is the best choice, but only AFTER you got her to 7*, because she have extra hit from her sphere Lexida, and auto angel idol buff extra skill. As for the other units for arena, any will do, since you don't have that many units yet.

for questing, any unit will do, especially if you're aiming for Exp grinding, just turn on auto-battle, and leave it be.

as for mecha gods, considering you still have low cost, units that you MUST have in your squad is : mitigator, and defense buffer. right now, the only mitigator you have is darvanshel, use him. and ask for help from your 7* friend, preferably one that can kill the mecha god quickly, but also provide HP boost.

Trials differ from each other, not all the same. you need different units and squads for each trial, and looking how small your units right now, I suggest you do more summoning before going to attempt trials. But, for Trial 001 and 002, it's still easy, so you'll be able to clear it with your current units.

Hope this helps :)
