I think this would have more success in the Bird ID subforum - which is dedicated exactly to such questions.

I think that on the first question, the focused adult and the immature in front if it are both Greater BBG while the second photo of adult could be Lesser BBG (definitely not a Herring), just based on bill sizes - but I am insecure about big gulls and always like to see all parts of the bird. UK people will be much better at this.
