As far as the NFL is concerned, if both wide receivers are on the same side of the field and on the line of scrimmage, the formation is illegal. There must be 7 players on the line of scrimmage and 3 players on each side of the center. It sounds like your question is describing a situation where there are 4 players on the line of scrimmage on one side of the center and 2 players on the line of scrimmage on the other side of the center. If this is the case, the formation would be deemed illegal and result in a five yard penalty being called against the offense. It is illegal to have a receiver 'covered' by another receiver on the line of scrimmage.
On the offensive side, nobody has to be in a down position on the line of scrimmage, but there must be six men on the line. The defense does not have any regulations as to where they must line up on the line of scrimmage.
It is on the offensive side of the ball, across the line of scrimmage. It is called off sides or neutral zone infraction.
this depends on the formation but usually about 15 yards back from line of scrimmage and about 15 yards from the side line
There is no "right" side of the line of scrimmage. The line of scrimmage runs across the field from sideline to sideline. All eleven players from the offensive team begin the play on one side, and all eleven players from the defensive team begin on the other side. Either side may appear to be the "right" side, depending upon which goal the team is defending and/or which side of the field the spectators are seated. If, however, you intended to ask if 9 players from one team can line up to the right side of the BALL, the answer is yes, though you would still need seven offensive linemen, and you would not have an eligible receiver nor any protection on the left side. Such an alignment might be interesting, but would be essentially useless.
Umpire. Not a baseball umpire. A football umpire. In football, the field officials are the referee, umpire, field judge, line judge, back judge and side judge. The referee stands behind the quarterback on the offensive side of the scrimmage line, while the umpire stands directly across the scrimmage line in the secondary of the defense.
That depends on the angle the ball travelled. If the receiver is behind or exactly to the side of the quarterback and the ball travels at an angle parallel to or away from the line of scrimmage, the throw is considered a lateral and would be a fumble if the receiver did not catch it. If the receiver is in front of the quarterback and the ball travels at an angle towards the line of scrimmage, the throw is considered a forward pass and would be an incomplete pass.
Depends on the formation and or play, but most of the time they line up on either the far right, or far left side of the field (not crossing the line of scrimmage).
One nonmetal that is on the wrong side of the zigzag line is Hydrogen. While it is usually placed on the left side with the metals, it is a nonmetal.
The line of scrimmage is an imaginary line passing through the foremost point of the ball after the ball is marked ready for play. The space occupied by the ball is considered the neutral zone. The defense must stay on their side of the neutral zone and only the snappers hands may be in the neutral zone for the offense. Measurements are taken at the foremost point of the ball and the foremost point must touch the goal line for a touchdown.. When an offense is running out of its own endzone it must get the ball completely out of the endzone or it is a safety.

If a quarterback and the entire ball are in front of the line of scrimmage then a forward pass can no longer be thrown but a lateral is still a legal play. However, by the act of crossing the line of scrimmage, the quarterback does not lose the right to throw a forward pass as long as after crossing the line scrimmage, the ball returns behind and is thrown from behind the line scrimmage.
