Anyone able to help with these ones? I think at least two of them are Common Blues but am not sure about all of them.

Many thanks

Sheesh, those poor butterflies have had a hard life! Guessing at no 2 to be a green underside blue. This butterfly isn't found in the UK, but looking at my field guide, the brown border inside the white fringe suggests that to me.
No 4 might be a very worn chalkhill blue.
