The top photos could well be GG's. I've raised them and yours have the GG look which shows the triple influence of bluegill, green sunfish, and red ear sunfish. The brightly colored anal fin is another common characteristic on GG's.
If they are GG's, they would fall into the "Sunfish, other hybrid" record category and would not nearly break the current record of 1.73 pounds and 12.5 inches. I've raised them to 12 inches myself....but its worth a try since you have the documentation.
The red ear influence, which is clearly visible in your photos, is, IMO, what distinguishes those fish from just a green sunfish hybrid. The GG shows the triple cross characteristics and actually, in my experience, I've never seen all three characteristics that didn't have GG somewhere in the lineage.
