Yellow is an asterina starfish. 

Purple appears to be some sort of (harmless) filter feeder.

Blue appears to be a majano anemone.

Clam or other bivalve. They don't open very wide because they would expose their guts to things. Clams don't work like they do in cartoons- they open just enough to filter water. A gaping clam is a sick clam.

That's absolutely some sort of bivalve. It doesn't really matter if it's a clam, oyster, or what- all the ones that are shaped like that are about the same. They filter-feed tiny particles from the water. In some tanks, they do fine on their own. In others, particularly newer tanks, they run out of food and starve. You can try feeding it and any others phytoplankton, if you're set at all on keeping it alive. If it ever stops closing its shell on being disturbed, it's dead- it should always shut if you do something like firmly tap on it.

The blue circled one is aiptasia.

Looks more like a majano, though hard to tell in this photo, and this post is over a year old.
