Help ID please

I have 2 coral to id that came on some LR I got with new tank. I think they are the same but I have 2 different ones. There are also some other creatures I am not sure of. Can help me id them please? There are 6 primarily white ones and 2 tan/brown ones.
 
Thanks BIO. I think the colt coral is probably the one, but I can't quite decide on the fuzzy mushroom.

Anyone else have ideas?
