Would you advice me getting a set of disc brakes (mech) from a DJ bike??? I am afraid that the rotors may not be true or parts may not work as well as a result of the impact from dirt jumping....

what do you guys think?

I wouldn't think DJing would abuse a brake more than other types of riding. Rotors are an expendable part anyway, and jumping doesn't generally involve prolonged braking.

what about from the impact?

only if you crash and land directly on them!

Dirt jumping will not stress your rotors/brakes hardly at all, unless you consistently land extremely off-camber and weigh a ton. Even then, it's not something I would worry about- rotors are easy to bend back into shape.

Don't worry about it. I have never damaged a brake/rotor and I've been DJing for quite a bit(going on my third year of serious riding).

The only thing that may have happened is that the cable may have stretched quite a bit if the bars spun around a few times on a crash, but that's a very inexpensive fix.
