Q: 6. can I use these screws to screw a Sirui TY-5DIIIL L-Bracket Plate to my Canon 5D III camera?

A: The person who answered the question before me is correct. It depends on how thick the floor of the plate is. Notice that the screw has a reduced diameter portion between the threaded portion and the head. That portion is 1/4 inch long. I made my own camera plate in a machine shop. I made it so that the plate is 1/4 thick. I did not have to use any spacers or washers. B & H has shorter D-ring screws that have a shorter reduced diameter section. Check how thick the floor of your camera plate is and get either a longer or shorter screw.
