Help me identify these please

[Reefscrub]

Hello. I am a nurse from Kalamazoo michigan. I just got into reefing after maintaining freshwater tanks for over 10 years. A friend gave me these four frags and I'm hoping someone can identify them.

Welcome to the Site! I've learned SOOOO very much on here, hope you do too!

Going from left to right top to bottom:

1. Green Star Polyps (I have a rock completely covered with this stuff, looks like grass!)
2. Some sort of Branching Montipora
3.Some form of a Favia
4. That's a tough one, maybe a Cup/Pagoda of some sort? Never seen that color though. looks to have polyps like it though. More knowledgeable members may help on that one!

Dang, after reading your screen name I have TLC playing in my head.
