The only thing delivered to the second stage from the first is IP gas - so long as your first stage is delivering the gas within the acceptable operating range for the second stage, brand is irrelevant.

Any of those combos should work fine... unless someone has done some tinkering to mask a problem. Just check them out BEFORE a dive (like a pool) so you know you won't have a tendency to free flow. All of the secondaries are down flow valves so do not need any other considerations.

of both first and second stage and you make sure everything is connected properly and to the right ports, you shouldn't have a problem.

Checking the reg prior to going into the water, is always a good idea (but it doesn't have anything to do with you question).
