First is idk, it's to hard to tell in the picture. Second looks to be brown montipora digitata. Third looks to be radioactive dragon eyes and whammin watermelons and the fourth don't look like they are a named variety. I'd try and get your nutrients in control and the color on those sps should come back. What lighting are you running?
2white 2actinic T5HO. i have no algae problem. the algae you see on the sps coral came with the frag and it's been months since i placed it in the tank and it has not grown or spread over the tank.
The brown on the sps was why i said nutrient control but it may be your lights if the frags are acros. Like I said I can't really tell from the pic and sps can be kinda hard to identify.
