Your water will be fine for the Rams... unless you intend to breed them and then I would suggest dropping the ph a little to under 7. As for the Cories, they should be fine... unless the Rams do spawn and then the tank will suddenly be too small and fish will start dying! I keep Cories in all my tanks but remove them if someone looks like they will spawn because they don't know enough to stay away and will try to eat the eggs also. Then the parents get really pissed!
I say all that with the assumption that these Rams are tank bred and raised... that is what you want. I'd stay away from wild caught Rams as they always seem to have internal parasites that will kill them and they are much more aggressive.
Good luck,
