A resultant force is the equivalent force, of two or more individual forces that act on the same object. For example, if somebody pulls with a force of 100 N due north, and somebody else pulls with a force of 100 N due east, the resultant force would be about 141 N, due north-east. Calculations are done with vectors; specifically, any vector has to be separated into components along the x-axis and the y-axis (and the z-axis, in a 3-dimensional situation), and the components are added individually.
if like parallel forces and unlike parallel forces acts on body at same time what is their resultant force and resultant torque
The magnitude of the resultant can be anything between 5N and 15N.
the head to tail rule
I'd call it the resultant, but "net force" is a good name too.
"Balanced forces" means that the sum of all forces acting on an object - i.e., the resultant force - is equal to zero.
if like parallel forces and unlike parallel forces acts on body at same time what is their resultant force and resultant torque
The magnitude of the resultant of two like parallel forces is the sum of the magnitudes of the forces and its direction will be same as the direction of the parallel forces.
The magnitude of the resultant can be anything between 5N and 15N.
If the resultant of all the forces acting on a body is zero, the forces are called balanced forces. 2 types of unbalanced forces are naet force and resultant force.

no
The result is called the Resultant.
