Wow Sunshine must be hot!...Nobody has ever given me $100 worth of free corals before.:D
I agree with the first 3 pics. Biff is right.
But depending on how long they've been in your tank
#4. May be Millipora or a Stag --If it starts to grow long hairs out of it when the lights come on and it gets acclimated to the tank, it's a milli. If it stays "bumpy" and branchy like tree limbs it's a stag.
#5. May be a digitate coral..That's what I'm leaning toward.. if it has very tiny bumps on it...If it get's kind of fat and "fuzzy" under the lights then it's a pocillipora. But I believe that's a digitate coral.
As far as number 4 and 5 go...They like alot and very turbulent flow, and high lighting...acclimate them at the bottom of the tank, and begin to move them toward the top of the tank. They're SPS, so the water needs to be perfect, however these sps corals are a little more tolerant of nutrient rich water, so you should have pretty good success. On the flip side, SPS can be more difficult to care for than "softies" so if you wake up one morning and they're bleached white...Don't get too upset.
If they are acropora, acros tend to be very intolerant of any type of change in water conditions.
Here's my disclaimer: I have old eyeballs, and your picture taking skills leave a little something to be desired.:D
Great pick ups...
