Help with coral or pest identification.

Good afternoon everyone. I am not sure of this is a type of coral or pest please help. I will post the best pictures I can get. Sorry one of my crabs is beside it.

Pseudocorynactis caribbeorum aka Caribbean Mushroom.

Not a pest. They are usually under a rock out of sight. They do eat pods but are a normal part of a reef.

Can anyone help identify the other corals?
