Coral Id+a few issues

[unbeknownst]

The first issue I have is with the dragon soul favia. He has what looks like sand or mineral deposits in his mouth. I tried removing them already but they came back.

The other three coral pictures I need a general identification so I can take care of them properly.

The last issue I have, evident in some of the pictures is algae growing on some of the coral frags. I have tried Hydrogen peroxide dips which only help for a little while. I was told by the lfs to lower phosphates from .4 to below .1, and I just achieved .18 today over the course of two weeks.

Thanks for y'alls help in advance!
