Fortunately, it sounds like most of the scratches you are seeing are minor, and not reducing presentation quality. But you should still let the lab know that you are finding so many. Maybe some piece of lab equipment is causing a small scratch, but it could grow into a serious scratch, so the lab would appreciate the information. If you know which lab processed the print, send them a note and maybe some photos of the damage. If the scratches are always on the same side of the film, or in the same place, this is useful information to help the lab find the source.
With a new print, a lab scratch will typically extend from the leaders into the picture. If there is a leader splice, and the scratch is not on the leader, it's likely the film has been previously projected in a theatre that had made up the film into a larger roll or platter. If the scratch is only through part of the leader and extends into the body of the picture, it likely was caused during inspection projection at the lab, or in a previous theatre using changeovers.
A white scratch or white "shadow image" dirt is typically on the printing negative, and will affect multiple copies.
When a reel has a problem that seriously degrades presentation quality, you should definitely ask for a replacement reel immediately.
