First down, fourth down, it doesn't matter. A player's eligibility is determined my number and position. The number of the down has no relevance.

If I am, If one of the two ends or both of the two ends is off the line of scrimmage are they still eligible?

If a player is not on the line of scrimmage he can not be an end.
