coaching box questions

[Moshiner1345]

Okay a few scenarios for everyone. NFHS rules and may I please have rule references please or case scenarios.

Team A head coach gets a direct technical. He loses coaching box privileges. Can the asst. coach stand up and coach, or does he also lose coaching box privileges? What about if team A's bench personnel wants to protest, can they stand up the rest of the game?

Team A asst. coach gets a technical, indirect towards the head coach. Does the head coach lose coaching box privileges? Can the asst. still use the coaching box?

Dunk during warm ups, indirect towards the head coach. Does the head coach lose coaching box privileges? What about the Asst. coach can he use the coaching box?
