Gull ID, C Poland (1 Viewer)

Would it be possible to ID these gulls found this week in Poznań, C Poland please?

the left two birds in first pic both look good for 2cy Caspian Gulls, despite their obvious differences in plumage pattern. the rightmost bird has pale eyes and is difficult to assess, bill is too short and slightly malformed, a 3cy bird, rather head streaky, so maybe a 'cactus' (hybrid HG x cach); this also applies also the two birds in the 2nd pic - bill shape in the right hand bird is a bit bulvous at tip and wingpatterm is not conclusive, an adult bird however. left one is a 4cy type whith pale irides and greyish but stout legs, not so good for pure Caspian, so maybe a HG or hybrid.

Thank you very much for the help. As someone that's from the south of Poland I'm used to seeing pure Caspians, so was a bit stumped with these.
