Regular users are those who have either not logged in or who have not been configured to be administrators.
These users can see all of the interactive parts of the UI (i.e. Pages) and can open other apps (icon at the upper right hand corner of the screen), but they cannot see any of the administration interfaces nor can they access the administration functions through the REST API.
