New frag ID confirmation?

[MAH]

Hi, I picked these frags up last week. I thought I knew what they were, but now I'm questioning myself.

1) I thought chalice, but no sweepers?
2) Can't figure it out?
3) I thought chalice, but it sends out sweepers that are up to 5-6 mm long?
4) Favia?

Favia.for sure on the fourth.. the first 2 appear to be chalices.. third I forget the name.

Ok, is #3 a Favia with the sweepers and #4 is an Acan?

1. chalice of some sort?
2. Merulinidae sp; cf Paragoniastrea australensis
3. Favites pentagona
4. Lobophylliidae or Merulinidae sp.
