First one looks like a bubble coral...
3 looks a bit like eye of rah zoos and 4 looks like an armor of the gods paly. The second is confusing me cuz of the tentacles, i am eager to hear what it is when someone id's it. I cant tell but the shape and tentacles lead me to think it an lps just not sure what.
the second one reminds me of a hydnophora but the colors and shape make it weird
it could be some kind of psamcora
#2 is a pavona coral. I have one myself.
