cat /etc/passwd | less
will display a list of users, many will be system users, so possibly not what you're looking for

change the normal user to administrator
this is not so simple and depends on your distribution (you could put this in your LQ profile).

This might be as simple as adding the user to a group (maybe admin).

So you've got three redhat installations, one of them enterprise, but you don't know how to administer them?
If you've got Enterprise Linux, why are you not asking Redhat for support, isn't that what you paid for?
Or this is homework?
Or perhaps it is not your system?

In any case, I've no experience with redhat, so can't help you any more.

I guess that making the user a member of one or more special groups will do.
man usermod

There are no real "administrator" and "normal" users (like in Windows). On Linux, you only have one
administrator, "root", who governs all, and a bunch of normal users.
These normal users can be given special access (via a multitude of mechanisms) to certain programs, files, etc if needed. Usually, user groups are created to group users with similar access.
A group of "administrator"-like users is thus possible. If you have such a group, you can add usermod or edit /etc/group and/or /etc/passwd to add users to the group.
If you don't have such a group, you should consider what the user may (not) do, may (not) have access to. Based on that, you can define a proper policy (file permissions, sudo, etc).
