If you're asking if it's possible to see more than one user in the who command, the answer is yes. The entire purpose of the command is to track logged in users. Now, the question is whether the permissions allow you to see other users or not.
Yes. A Linux boot disk will allow you to change passwords or completely bypass Windows security and access the data directly.
crontab -e
The su command is used to assume the permissions of another user. Without any parameters, it is used to assume the superuser, or root, account. When followed by the name of a user account, it will allow you to use that user's account and permissions.

setuid is a unix access rights flag that allow users to run an executable file with the permissions of the executable's owner and to change behavior in directories. These (setuid and setgid) are often used to allow users on a computer to run programs with temporarily elevated privileges in order to perform specific tasks.
