Offsetting penalties are when both teams have committed a penalty on the same play. Offset means the two penalties cancel each other out.
Offsetting penalties only occur on LIVE BALL penalties. These are flags that occur during the play (after or concurrent with the snap, before the ball is dead at the completion of the play). These are penalties that are not whistled dead at the snap, or flags after the play (usually unsportsmanlike, late hits, etc...).
If a live ball foul occurs on both the offense and defense, they 'offset' meaning neither foul will be penalized, and the down is replayed.
If multiple dead ball fouls occur between plays on the offense and defense, ALL fouls are penalized in the order in which they occurred. While it may seem like it wouldn't matter (if both the offense and defense had unsportsman like fouls at the same time during a deadball phase), since they yardage is the same going both ways, there are special exceptions that can happen.
For example, if you have two (one on offense, one on defense, with the offenses one happening first) dead ball unsportsman likes penalties, and the ball is at the offenses 20 yard line, the result wouldn't be at the offenses 20 yard line, but the offenses 25 yard line. The reason is that the 15 yard penalty is first against the offense, and since the ball is inside the offenses 30 yard line, the penalty yardage is half the distance to the goal, which would be 10 yards and place the ball at the 10. Now you assess the defenses penalty, giving the offense 15 yards, so the ball is placed at the 25 yard line.
The Penalty for being offsides is five yards.
It is an indirect kick for the defending team from the spot of the infraction (usually where the offside line was when the infraction occurred).
An indirect free kick will be awarded to the opposing team at the location where the player was guilty of the offside infraction.
5 YARD PENALTY
5 yard penalty
Yes, the interception will count. The key is that the penalties happened after the change of possession.
You usually have to re-kick.
In the eighties the NHL created a rule which was referred to as the Gretzky rule or one to prevent the Edmonton Oilers from having more open ice. Basically it was designed to have teams play five on five with offsetting penalties as opposed to four on four or three on three. That has been changed so that now with offsetting penalties the teams play four on four.

Penalties ensure that players (and sometimes coaches) have a clean and safe football game.
