Cleve, didn't mean to ignore your cry for help! I only saw it today.
I think I can help you with a few.
1) A. loisettiae, this is a typical colouration for the coral. Similar is A. pulchra, but it is generally a bit heavier in build plus, A loisettiae has radials of the same size, A. pulchra has mixed sizes..
2) no idea. Sorry.
3) Not A. millipora, but may be a close relative. My first impression says A. abrolhosensis, as it is a staghorn type, rather than corymbose.
4) A. tenuis. Typical colouration for this coral. The scale-like radials are arranged in an even rosette, while its close relative A. selago has the radials in a scattered pattern.
5) could be A. formosa. The branches look like it with evenly distributed radials, but the main stem has corallites of various sizes, which A. formosa can have.
Hope this helps you out.
