What are these called?

First picture is star polyps, second is anyone's guess

 

[Crabs McJones]

Green star polyps. Be careful where you place them, they grow like a weed and can take over a tank quickly.

 

[PAXpress]

Yep both are definitely GSP

Are they okay at top of the tank?

 

[Waters]

They will pretty much grow anywhere.

should be fine at the top or wherever. I'd recommend isolating them on an island.

 

[Michael Cronmiller]

Gsp they definitely spread quickly

 

[enaldy]

Yep.. GSP.. be really careful with this one, put that rock away from anything else lol. They spread like crazy, I have seen tanks been completely taken by them.. but they are cool thou! I have mine on a rock not touching anything else, kinda like an island.

Also on the first pic you may have an aiptasia anemone (can't see it very well, just the tentacles of death lol)... I would kill it asap too!!! They are definitely a no no for any tank..

I like natural solutions.. i would go with the shrimp first.. if it doesn't work go for chemicals
