ID on 2 nems and 1 starfish

[40B Knasty]

Are these anemones and what kind?
Is this an astria starfish and what kind? It has some interesting colors on it.

To me the two anemone-like things look like a ball anemone(a type of mushroom coral). And the sea star looks like a asterina starfish(I don’t know the specific kind).
