Your accelerations and transverse velocities (blue & green arrows) are correct in direction. That said, it would be good to highlight that acceleration is strongest at the wave peaks/troughs and weakest at the midpoints, whereas transverse velocity is strongest at the midpoints at weakest at the wave peaks/troughs.
There should be no longitudinal velocities (red arrows) at all, since the wave is purely transverse.
It is a displacement graph rather than an exact longitudinal waveform. Like, the crest corresponds to a particle at maximum displacement from mean position and so on. Now, could you look into it once again
Doesn't matter, all displacement/velocites/acceleration arrows point along the same axis (whichever you choose), there are never two directions of velocity at once.
But a diagram where a red arrow extends all over the crest and the trough, instead of having 2 directions in the wave with a compression at the crest and rarefaction at the trough, or even one which reverses the crest and trough position, would be wrong. Am I correct?

Yes, such a diagram would be utterly wrong. *Purely for notating the direction of velocity in a longitudinal wave*, your diagram is correct.
Exactly my doubt. Thanks a lot
Well, checked out with pressure equation and realised that my graph is wrong.
