I can help with the first airplane at the top of the page. It is a replica of Lt. Rudolph Stark's DVII. It is at the National Museum of the USAF at Dayton, OH.
The 3rd one from top DVII(F) has Serial # 461/18 or 461/19 I dont know the pilot but i would think this was probably of Jasta 21 or Jasta 66. I tend more to Jasta 21.
