In the spirit of the game, yes they should, but to be able to sign your card, they must have witnessed every shot you hit, not necessarily where your ball goes.
Some players don't help their opponent search for the ball, which you should, and some when they find it don't tell their opponent where it is, which is against the spirit of the game.
A fumble is down when the recovering player is down or when the ball goes out of bounds...so yes, if the ball is fumbled forward and recovered by the offense, or goes out of bounds, past the first down marker, it is a first down. The exception is on fourth down. In the NFL, only the player who fumbled the ball can advance it on fourth down.
The marker is placed by the player when the object ball is the 8 ball under APA Rules. There is no location prior to the player placing the marker, as it is typically in their pocket.
yes in paint ball they call it marker but it really is just a paint ball gun
a marker that is flat so a ball can roll over it
In the game of 8 Ball, a marker is required under APA Rules to indicate the pocket where the 8 ball is intended to be pocketed. The marker can be any item placed by the player on the rail except a piece of chalk, because these are found on the rail.

Yes, each time the shot is made to pot, or pocket, the 8 ball, the pocket must be identified. Under some Rules, this requires a marker to be placed. Under these Rules, the marker must be placed or replaced prior to the shot - a marker left in place from a previous shot and not touched is not a valid marker.
A ball marker can be as big or as small as you want. Although common sense prevails obviously. The average size is a circular object the size of a British 10p or American quarter.
