Well, two out of the trhee are not really the easiest of corals to keep. The Sinularia should be cool though. Stable parameters, efficient lighting and a routine... (one in the same)
Here's a couple links that might help. GL.

Stabilize your system, your alk is all over the place.

what about that flowerpot keep closing it self up ?

 

[TangingOut]

They close themselves nightly. It's when they stop fully opening when lights on is when they're in trouble and start going downhill fast.

do i need to feed them or the supplement that i give them is enough ? (phyto plankton and zoo plankton )

Po3 above 0.25 will lead to stunted growth and "coral retardation" .
I would get some GFO and a low range test kit and start there.
