We've all been there. I'll try to explain as we go along. If you want to read 
up about what the commands do you can read the man pages (online 
documentation):
	man yum
	man rpm

You just queried the package manager to find out if package nx was installed. 
This tells us it is, and gives us the version number.

yum works with rpm to sort out dependencies and look after upgrades available 
from the repositories. This command would install package nx, but because you 
already have the current version installed there's nothing to do. When you 
did 'yum install freenx' yum worked out that freenx needed nx and installed 
that as well.

That's a lot of repositories by the way, and you probably don't want them all 
enabled. Anything with testing or debuginfo in the name is probably a bad 
idea if you're new to linux.

A more detailed rpm query, this time listing the files provided by package nx, 
then searching the results for the string nxagent. This looks right.

So now we know it's not because nx isn't installed, and can look at other 
causes. A possible one is SElinux which has a habit of making things fail 
without clear reasons. You could try temporarily disabling it using:
	setenforce Permissive
If freenx works after that then there's your problem. 
You never posted the logs from the user's home directory, and they might also 
have a clue. Look for logs 
in /home/<username>/.nx/C-<servername>-<display_no>-<session_id>/
