It's even hard to say conclusively that all 4 are really 249 Sqd. Some folks would see 2 of those planes as having 1 instead of T for the squad code, and say they were survivors from 601 Sqd's
Wasp batch that hadn't been repainted yet. OTOH, given they all have new-school roundels and 1 has clipped wings, it's probably safer to say they've all got the T of 249 as of the latter 1/2 of 42.
As to colors, they all look to have 2-tone camo scheme, in the mirrored pattern on the 3 closest planes, but I can't tell that on the furthest one. I'd wager they're all in desert camo mostly due to the color of the spinners, which all look red to me more than they do any other possible color. The leading plane is probably older and is more faded than the others, or the others have recently been repainted.
That brings up #4's left wing roundel. If I had to guess, I'd say it was in the process of being repainted. Looks like they went over the blue ring with a light primer, then repainted the upper wing camo, overspraying the 8 o'clock area of the roundel primer, but hadn't gotten around to applying the final blue on top before this sortie.
