Hello, I have a game which has multiple projectiles flying at specific targets, but i want to make it such that, each projectile can only collide one particular mesh each.

As in each projectile can only collide with its own specific mesh and none other.

Any help?

Unreal has Collision Channels to specify the behaviour of an actor when it collides (if you want it to collide) with another actor.

I suggest to study this article: Collision Filtering - Unreal Engine
