Which Variants is my roster ready for?

I have a Warlock down there that I recently got that I haven't had a chance to rank up. I've done v4 completion and nothing else so far.

Variant 2 completion, Variant 4 exploration (assuming you have 1* Hulk). Maybe V3 and V5 but I don't think that's going to be fun.

would 4 star Ghost for v3 and 4 star claire be helpful for v3 and v5 respectively?

By the way, I'm asking roster wise, not the strength, I'm gonna be upgrading HB, Starky, Doom, Warlock, Havok, and Cap IW further as much as I can as soon as possible

In that case, all Variants can be explored... I'd focus on V4 for now.

Well I think ranking up Doom, Venom and Stark Spidey is very wise and then you should jump into V5.
Do you have a Sentinel in your roster?

I don't unfortunately
