Where the box is mounted on the surface, direct metal to metal contact between the device yoke and the box or a contact yoke or a self grounding receptacle shall be permitted to ground the receptacle to the box.Normally you'll need afci protection and gfci protection in certain areas. Not sure if you used devices or just don't have none at all. Personally i would prefer to use the ground bus you circled solely for grounds.
