Welcome!
Your pink phalaenopsis I would repot in bark like the white one and treat it the same.
It may already have root damage so don't be discouraged if it does not survive.
When sphag moss is too wet it will suffocate the roots and you can read through the forum here about phals for more details on that.
Repotme.com has great bark mix and videos on how to repot phals.
The Phal bellina is different. I would pot this in sphag moss! It needs to be more humid than many of the phal hybrids.
Furthermore, it needs to be warmer and give it less light.
I like to mix the sphag with medium perilite to keep better air spaces and don't soak sphag moss when you water it.
Good luck
