I was wondering something, if I have the same molar fraction for two different substances for a vapor on top of a solution, will this mean that the pressure of each individual substance will be the same ? Since they have the same quantity of molecules ?

This question has a link with Raoult's law : Psolvant= X solvant * P^Osolvant

Please elaborate, what you wrote is ambiguous.

In general, if I have the same quantity of molecules for two substances, will these two substances have the same pressure ? (in vapor state)

That's a direct application of Avogadro's law, it has nothing to do with the Raoult's law nor solutions.
