Your flight pics are of two first winter large white-headed gulls.
The left hand bird in pics 1 and 2 and only bird in pic 3 is Heuglin's Gull because of its darker barred underwing, broad tail band and lack of clear cut pale window across the inner primaries [even from underneath].
The right hand bird is Yellow-legged [Mongolian] Gull based on its whiter underwing, narrow tail band and heavier bill.
