[Patton]

Not quite:

In a)dead ball foul, administered from succeeding spot which will be the start of the 3rd quarter, and R9 is ejected.

in b)and c) Rule 8-3-5 states "If during a successful try, a foul by B (R in your case) occurs A is given the choice of: a. accepting the penalty and replaying the down; or b. accepting the result of the play and enforcement of the penalty from the succeeding spot."

So in b) 15 yards enforced at the start of the third quarter or replay the try from the 1 1/2 yard line.

And c) 5 yards enforced at the start of the third quarter or replay the try from the 1 1/2 yard line.
