Is there a Number of running RQM adapters limit in the same machine?

As long as you're careful about naming, directories, etc. so there are no clashes, I have not found a limit to the number of adaptors you can run other than memory and CPU.
One thing you may want to investigate if you haven't already and that's the ability to run the adaptors in multithread mode, which allows for multiple test runs at the same time. It may save you some resources.
