@rd1027 Animal Man isn't really over the limits and as long as his protozoa mimicry is limited to 10 dupes like everyone else, it should be fine. Though he shouldn't be able to stack from multiple animals to beyond limits.
Southern Cross is a telekinetic well below Jean Grey.
Comet is Cyclops with flight and super strength but nothing out of the limits from what I can recall though I last saw him awhile ago so that may have changed.
Blue Devil is just Etrigan-Lite and not really outside the limits but he will ruin most demons' days.
