You yourself specify both the names and the passwords, in the files above, and you yourself tell each appropriate person their UserID and password.
If you want to restrict access to a single group, and password security is not a concern, then just make up an entirely new username (like ``appm4350'') and a password of the appropriate level difficulty for your purposes.
On this academic web server, it rarely makes sense to make multiple usernames/passwords unless you are dealing with multiple individuals/groups with mixed access to multiple directories. In that case you might be interested in reading about password services to a group of users.
