my friend cannot post yaar

[HalloIsBack]

It's "Dost" and some indians used that as well. I believe the Pashto word for friend is "Andywaal."

dost/dust => dari/farsi

and what about the pashto word malgeraj?

That's mostly used by Southern Pashtuns. However, most Pashtuns use Andyiwaal to my knowledge. It's different dialects, that's all.
