QA-APP-8: Everyone in my playing group is a certified official. Certain rules require either two players in the group or an official to make the call. Can just one of us make these calls since we’re all officials?

No. To make calls during tournament play, you must have been authorized by the Director as a Tournament Official. Passing the test does not make you a Tournament Official (referred to throughout the rules as an Official). Additionally, Officials have restrictions on making calls depending on whether they are playing or not. An Official (including the TD) who is playing cannot act as the sole Official for calls that affect players in their division. A non-playing Official can be the sole person to make a call where rules indicate an Official may make the call. A spotter can make calls (for example, regarding the position of a disc that has gone out-of-bounds) if they are also an Official. If they are not, their call should be considered as input for a group decision.
