Is there any method to evaluate resultant effect of number of non-coplanar forces acting simultaneously on a body.

Here is the methods to find resultant for coplanar forces.

Yes, of course.
There are many methods.
Resolution is the most common for hand calculation, but remember that there may also be a resultant moment.

Set your question into context for a more detailed answer.

I don't understand what the problem is here so I'll just say this: The result of applying any number of non-coplanar forces to a particle is the same as the vector sum of all the forces acting on the particle. However if the object is not a particle then you have to deal with the problem of the forces being applied at various places which would then contribute to angular momentum so energy that could have gone into translational kinetic energy will go into rotational kinetic energy. It's a very complex problem with no general solution. You have to take each problem as a unique situation.
