Did you catch all of these Sunfish in the same location? The reason I ask is because if the Pumpkinseeds and the Bluegills are in an isolated habitat together, there might be a slight chance that some interbreeding has occured. Here's what I suspect.
In post #1 the 4th pic is more than likely just a nice female Bluegill. BUT the rest of these might be a type of hybrid. I suspect a Bluegill Pumpkinseed cross of some type. While most all of them look like an average Bluegill in terms of mouth size, body shape, and dorsal spines, they have a very unusual mottling and extremely Green appearance. Many male Bluegill that I've seen that are this size almost have a copper irridescence to them ,and these look to be very Green in their mottling, almost like that of Pumpkinseeds. So with that said, all of the potential Bluegill photos MAY be some kind of BG/P-Seed hybrid, but I am not certain.
Post #2 1st pic female BG if not a hybrid.
Post #8 1st, 2nd pics female BG if not a hybrid. 3rd pic juvenile male. 4th pic Male. 5th & 6th pics male. 9th pics looks to be just a really nice large female Bluegill, but does not appear to have the same characteristics of what could be a hybrid.

I hope this helps. I have captively kept Bluegills, as well as Green, and Longears, and these don't look at all like any of the Bluegill/Green Sunfish hybrids that I've seen a lot of ponds stocked with either. I'm guessing that if what you are catching isn't just plain ole' Bluegills, then the Bluegills and Pumpkinseeds are intermingling. I definately don't think any of them were Green Sunfish, Red Ear Sunfish, or Longear Sunfish though. Excellent pics by the way!!! and GREAT JOB too!
The more I look at your photos, the less likely I am inclined to say that hybridization has occured. I think what you are catching is just some really beautiful and healthy Bluegills. That GREEN color is absolutly remarkable, and unlike most large Bluegills that I have seen, but I think you've got yourself Bluegill. The photos are superb though. You can see every last detail of color, and usually most pics don't show that off as well as your photos do. Absolutly fantastic job.
