Anybody in /etc/passwd is logically a user, but in general
ftp, mail, daemon, bin etc are system users,
used by daemons(background processes, run ps aux)
I dont have any idea about purpose of halt and shutdown users.
Try man halt or man shutdown.

You cant halt/reboot unless you login as root(superuser).
You can however reboot by pressing ctrl-alt-del on local
terminals OR switching the computer off ;-).
