You don't remove processes you remove programs.
And you do it with either the programs own uninstaller if it has one, or the add/remove programs utility in your control panel.
Stay away from disabling processes because if you disable the wrong one/s you can completely hose your operating system beyond repair.
The first three you listed are obviously connected with AOL.

You can uninstall AOL if you wish, do not mess with the Intel process and I recommend you check your system for malware.
Run the following free scan from Microsoft using Internet Explorer only:
Windows One Care Free Scan
Go to Windows Live Onecare Free Scan
It will say "Get a free PC safety scan"http://safety.live.com/site/en-us/default.htm
Make sure you click "Full Service Scan"
in the middle of the page and not the "Try It Now Free" on the right side.
Allow it to download an Active X component.
Choose "Complete Scan" in the window that opens
Do not click on anything else that offers you a free trial or to sign up if you live in the US.
Allow it to scan - it may take quite a while, maybe two hours or so depending on how big your hard drive is and how fragmented your registry and drive are.
