Hi and Welcome to LQ.

As you may know the 2 main users are root and user(insert username here)

The rest are, as you have listed them, System users.

They are for the system to operate and take little notice of anything else.

Most of the descriptions are there in your list. The others you can google to find out what they do.

I hope this helps, you may want to look up the "Linux Documentation Project"

http://tldp.org/guides.html

regards Glenn
