I think the things on the coraline are tunicates...

 

possibly hydroids from the 1st pic

 

The tentacle like things attached to the bivalve in the first pics are clear cup corals. Completely harmless and cool IMO.

 

did your rock come from the caribbean?

 

Pics two and four look like they might be an anemone.

 

i d k about where my lr came from i know he has grown them in a huge plywood tank hehas tons of it

 

That's an odd angle to try to use for ID on the bivalve, mainly because I can't tell how much of the pic is shell and what's just rock. However, it's probably an Ark Clam, most likely Arca zebra. They're your standard filter feeders.
