Coral?

[Burray]

I am attaching pictures of 3 new corals I purchased about 3 weeks ago. I'm not sure what they are called so if anyone knows that would be great also the bright green one is about a nickel size and the burgundy and green is about half dollar but they both look like they are getting a dull like film over them. The other looks like a mushroom almost clear with orange trim and bumps and that looks the same as when I purchased it. I think my calcium is the only thing that seems out of place a bit low. I have been using Reef Energy Plus about once a week and 5% water changes weekly. Any thoughts on what they are and what I can do to brighten again.

Green and burgundy corals are Favias and the bottom is a rhodactis mushroom. Mushroom probably got a little bleached from the move. Leave anything the way it is. Stability is key.
