Hello! The second one has was looks to be a KB 96 on it, and the green and orange one (only green and orange no yellow blue green and orange) has a TP 96 on it. The rest I do not believe have any signatures. #1 is 3/4”, #2 is 1”, #3 is 1 3/16”, #4 (yellow and red) is 13/16”, #5 is 1”, #6 is 15/16”, #7 is 13/16”.
