Before trying out Arya Linux, I would like to know from other members who already have tried it, if this Linux is as stable as CentOS/Slackware?

I have tried some of the Linux distributions other than CentOS/Debian, which I found to gets freezes & gives several problem.

This is another Linux which I recently come to know, so would like to know about its performance.

You have asked several questions like this. If you'd like to know about this distro, the best way to do so would be to load it and try it yourself. Bear in mind that you say/have said NOTING about any of your "freezes & gives several problem" in any of your other threads...both Debian and CentOS are VERY stable, so if you're having problems with those, you'll probably CONTINUE to have problems. Either your installation is corrupted, you're not installing it correctly, your hardware is going bad, or you're just not comfortable with Linux vs. Windows.

Unless you tell us what problems you're actually having, and work through them, installing one distro after another is pointless.
