Thanks to all who contributed. Am I correct in saying that for the 1-3 down exception, the only player who can use the exception is the snapper, but on 4th or the try, the snapper doesn’t have to be using the exception? In other words,he can snap from the end with a receiver number and be eligible.
Yes, the only player that *can* use the expection on 1st-3rd down is the snapper. However, the snapper doesn't *have to* use the exception on 1-3rd down, as long as there are still 5 players on the line numbered between 50-79.

Assuming 31/1 (holder and kicker) are seven yards back, there are 5 correctly numbered linemen, so #27 is not utilizing the exception. They have one fewer eligible receiver in this formation since the end is wearing an ineligible number, but it is a legal formation.
Additionally, if they overload one side:

Also legal and not utilizing the exception, regardless of down. In this formation, #27 is also an eligible receiver.
There is no requirement that a snapper in a scrimmage kick formation be (a) an interior lineman or (b) either numbered 50-79 or using the exception to replace a player numbered 50-79. They do have to be an interior lineman if they are using the numbering exception, but there is no requirement that they *must* use the exception.
