Recently I installed Xampp for my server needs of http, php, mysql, etc. and everything worked just fine. I was able to call the "mysql" command, connect and login to the SQL server and everything worked fine.

Now, I recently used yum-entender and updated everything that was in the list. I'm using FC5. After updating, it seems that MySQL doesn't work anymore. I get this error:

It used to work just fine though. Is there anyway I can remove FC5's MySQL, HTTPd, and other server software? All I want to use is Xampp without issues.

perhaps try finding out what the issue is
there should be a .err file in /var/lib/mysql
open that up, and it should tell you what's happening (prolly two mysql's running)

to remove mysql from fc5
try yum remove mysql
but it'll prolly complain of dependencies

so just try yum remove httpd php mysql
and then when it complains of dependencies, remove those dependencies as well, as long as you're sure you don't need them

OR...

try
ps -ef | grep 'mysql'
if something comes back, then there are mysql processes that shouldn't be running, as far as you're concerned (because mysql isn't working properly)
so then just kill those processes, and try starting mysql again, or removing, then re-installing
