Ok, I’ll stick my neck out and say that I think the one on the left is a Potez 29 Sanitaire (White with Red crosses) and the others are standard Potez 25 TOE in Khaki.

No need to stick your neck out John you are absolutely right! In my copy of ‘Dust clouds in the Middle East’ by Christopher Shores there is a photo of a Potez 25 TOE and a Potez 29 which has crosses on its wings of EO 596 at Deir ez Zor Syria. Both seem to have five light coloured bands on their upper wings as well.
