You must be confusing situation 1 with basketball. In basketball, an excess timeout is granted, but a technical foul is assessed against the requesting team. In football, requests for an excess timeout are ignored. Remind the coach he has no timeouts. If he doesn't stop then, or if he acts unreasonable, then by all means go to a UNS penalty.
To me, situation 2 (deliberately kicking a spotted ball) is delay of game on B. I would stop the clock until the snap, assess a 5-yard penalty to B, and remind the coach that if this action is repeated, it could be considered an unfair act.
