Your PS4 can have as many as four profiles signed in at the same time. If you want to add a new profile, you must log off from one of those profiles first. This wikiHow teaches you how to log off on a PS4. In the case that you log out of your PS4 without first logging out of the PSN, your account will automatically try to reconnect to the PlayStation Network as soon as you log into that account on PS4 again.
