They all three look pretty GSF'y to me.
The middle picture looks pure GSF. Harder for me to tell on the first and third picture but if they have some other sunfish in them the traits sure are heavy towards GSF. They all have pectoral fins and green cheek bars that look GSF.
It is easier to tell with them in hand than in pictures only. A pure GSF will not only have a big mouth but a wide body compared to a BG. The hybrid is something in between. But if you have a pure GSF and a hybrid side by side you can see that the GSF lacks the height of body the hybrid has but the GSF will have a wider (thicker) body.
It would be easy to call all three of those GSF but I would not be surprised if there was not some mix in the first and third pictures. Thing of it is, none of them look like traditional F1 HBG. If they are hybrids they could be F2's with a lot more GSF characteristics being exhibited.
That is my take but I am far from an expert. I can tell my own fish better than someone elses because if I question I can pretty easily get my hands on another fish that I am sure of the pedigree. Once I can compare them side by side then the hybrid becomes evident. I also know what my possibilities are by the fish I stocked so that helps too.
