Appears to be:
Adam Kinzinger, front row at the right (”Pilots”) t-shirt.
James Vasquez (looks like) with outstretched arms - left arm resting on Adam Kinzinger’s left shoulder.
Lt Col H. Ripley (“Rip”) Rawlings IV (ret.) at the rear, topmost in the photo.
Dr. Erin Felger (looks like) in the front row at the left.
Good eye..I’m less familiar with the others in the photo and iirc it was taken at Kinzinger’s home in Virginia.
