The one on the far right in the first image looks like a 2cy to me but I am unable to enlarge the image and it is very dark - the head/neck and tail are still quite dark yet there is yellow appearing at the base of the bill and the underwing coverts are extensively white with more ventral white feathers creating a mottled effect. Unfortunately the iris (a good aging criteria) can’t be seen). The single image, (presumably the middle bird in image 1 ?)is older, maybe 3cy the head is much lighter but still with obvious eye mask, the iris is pale yellow and the bill almost completely yellow, however the tail still has a very obvious dark terminal band. The bird on the far left looks like another 3cy (perhaps slightly more advanced?) with still again a dark terminal band on the tail, variable head flecking concentrated around the eye.
