The first one looks like a tabling A. loripes. It has the shorter axials, which A. granulosa doesn't have.
The second and the third do not show enough detail to be sure, but I would tip in A. plana or A. cythera. They may be the same species. Are the corallites open during the daytime? This is typical of A. cythera. A. plana tends to open only at night.
