Who are these extra users?

A few days ago I logged in as root but never logged out, just closed the
terminal windw by accident. Is there any way to logout? I don't see a process
for root (below) but maybe I screwed up? Why am I logged in 3 times? I know
I can reboot but I don't really want to do that if its not necessary?

With root listed is there a security issue?

Help!

Thanks,

Al
