Agreed with Brendan on the Grassbird; for the Warbler, I think it might be difficult to say without a clear view of the primary projection because Clamorous also occurs in Thailand. I'm not sure which is more common in this site... ^^"

You'd need a closer photo for a convincing case of Thick-billed - especially in that photo there seems to be an eyebrow and the bill isn't very stubby (jizz more like Oriental or Clamorous...)!
