1) Greater sandplover 2 + 3) Plain prinia 5) Lesser sandplover (center and right) Kentish plover (rear left) Terek sandpiper (rear). Unsure if the bird asleep to the left can be identified as the bill isn't visible, but feels like a Greater sp.
#1 looks like another Lesser Sand Plover to me, based on head and bill shape, white forehead, obvious supercilium and breast band. I agree with Lessers in #5 and I'm also unsure about the bird on the left.
Could #2-3 be a Rufous-fronted Prinia? The forehead seems quite rufous, to the extent that I had to double-check it wasn't a Tailorbird.
