Is it possible the large brown gull is Black-backed (Lesser or Great)?

Hi All!
I stumbled upon every gull in a field in Weld county, just west of Ault on
CR 33. There was one very large white gull. Could it be a Glaucous,
Iceland or albino gull? In the photos, there is also a very large brown
gull. Could it be an immature Herring gull?
