Here's how they would work in gameplay.

Freddy: Acts similar to Springtrap, use the audio button to distract him.

Bonnie: The usual movements, goes to the left door, close it until he goes away.

Chica: Will go to the right door, close it until she's gone.

Foxy: Will go behind your office, turn around and flash a light at him if he gets too close.

Puppet: Flash at him to prevent him to go into your office.

Golden Freddy: Appears sometime during gameplay, go straight to the monitors to make him go away.

Edit: There will be some...renovations going on.
