Gull Identifications - Chew Valley Lake, England 26.08.18

I struggle with gulls - particularly judging the alleged differences in bill size & structure and the variability of tertial patterns. So help with the attached gratefully received.

I have identified the first as a Great Black-backed Gull, the second and third as Herring Gulls and the fourth and fifth as Lesser Black-backed Gulls.

Many thanks

Paul

Agree on ##1-4. Think #5 might be another Herring, as it has pale notches on the tertials.

But I'm crap at immature large gulls as well, so don't rely on my guesses
