ctfmon.exe - this has to do with the language bar stuff and MS office.
even if you kill it, it will return.
just ignore it, it's harmless.
taskmgr.exe - that's the Task Manager
the others - i don't know.
but i suspect you don't have to get rid of any of them, they're probably all fine (part of Windows or applications you use).
avgcc32.exe - i'm guessing here, you use AVG antivirus?
you can learn about some of these at least in this site:
One Ring to rule them all, One Ring to find them,
One Ring to bring them all and in the darkness bind them
