a couple ids pleas

[greg1786]

hi...I'm new to keeping sps. in fact corals in general really the only coral I've ever had were some zoa colonies. I was recently given a birds nest and two others which I'm not sure what they are any help would be much appreciated ...
first two images are of an sps closed when I first got it three days ago and then almost fully open today

the 3rd image is a different coral I was told its called a green cats paw or cauliflower coral??

the first one isnt an sps by the looks of it - more of a soft coral - Brown star polyps - "Clavularia sp"
the last looks like green stylophora - Stylophora pistillata

If the first one has a hard blue skeleton then it is Heliopora coerulea. http://www.arkive.org/blue-coral/heliopora-coerulea/ if the base is soft and even purple tissue then i would say pachyclavularia violacea aka brown star poylps.

The second could be Stylophora pistillata http://coral.aims.gov.au/speciesPages/species_metadata/0345/view#.
