Hello! It looks like you are just starting out and need some good tips. Have you read the setting up a tank threads?
It does look like you have some "uglies" (just a term for newer tanks - not an insult) on the rocks so life is happening in the tank. Also looks like you have a leather in one of the pictures that has some polyps out.
First, make sure you keep parameters stable. It is key to success in this hobby. Now the GSP will be hardy. Even if one polyp survives, it will continue to grow. Leave it in the tank and let it be. It will close up as you mess with it or the tank.
The other corals you showed, the one is only skeleton, the other looks ready to be gone. The zoas, just give them time and do not mess with them. They should open.
Tell us about your system. Sand, rock, animals, filtration, flow (powerheads), lights, etc. FTS (full tank shots) will help also.
