As for GH and KH i have no idea what that is, I have a master kit that tests for ammonia, nitrite, nitrate, and ph.
You can ascertain the GH and KH from the water supply people, they may have a website, or they can tell you. GH is general hardness, KH is carbonate hardness also called Alkalinity. We need the numbers for these in order to assess what the pH is likely to do. And GH as well as pH does affect fish.
The wood might lower the GH/pH slightly, but not significantly, but here we need to know the KH as this buffers pH.
Back to the fish, you have a mix of soft water and hard water fish which is going to be problematic. Livebearers need the harder water, especially molly, or they will have health issues and likely premature death. Soft water fish like loaches are happier in softer water. We can discuss this more when we know the numbers for the GH and KH.
