Hello,
fiirst is a Reed Warbler, please note strong, nearly all pale bill and full,rounded tail. I see now Great Reeed Warbler here (should show strong supercilium, darker lores and darker, stronger legs) and no Locustella with olive tinge and unmarked plumage and long,straight wings.
Second and third, if different, bird is a Chiffchaff with blackish legs and blackish bill, short pp and olive-greenish upperparts and good head-pattern,including a narrow distinct eye-ring.
Edit: I think its to early for a Marsh Warbler ,even in Turkey?
