I would say all those should be 5$ or less per polyp.
Ive been selling rastas for 10$ per polyp but they gotta be good size and colored nicely. Overall, look good.
Just like any coral, zoas can be unhealthy and show discoloration, loss of skirt, and shrinkage.
I have some candy apple red zoas that look so bad in my tank but i keep them bcuz i think they will color up when my tank parameters are right.
