When all the forces of a force system act in one plane it is called coplanar force system. If the forces act in more than one plane then it is forces in space. In this case forces are not contained in one plane.
When all the forces of a system pass through a common point they are called concurrent forces. Thus we have concurrent coplanar forces when all forces are in one plane and pass through a common point. Also when forces in space pass through a common point we have concurrent forces in space.
Concurrent forces have a common point of intersection while non concurrent forces do not have a common point of intersection. Moreover concurrent forces act along the same line while non concurrent forces do not.
Non concurrent forces are those forces that do not have a common point of intersection and act along different lines of action.
¢The forces, which meet at one point, but their lines of action do not lie on the same plane, are known as non-coplanar concurrent forces.
how two forces are added if they are not concurrent but are acting in same direction
Non concurrent forces are those forces that do not have a common point of intersection and act along different lines of action.
Concurrent forces refer to two or several forces whose lines of action intersect at the same location, which then causes a rotation. These forces act in conjunction with one another.
Collinear forces are concurrent system type of forces, whereas parallel vector forces cannot be concurrent system type of force but they can be coplanar nonconcurrent system type of force
The magnitude of the resultant force in the case of the concurrent forces in equilibrium.

The magnitude of the resultant force in the case of the concurrent forces in equilibrium.
"Concurrent" means that it happens at the same time. In this case, presumably one force is applied at the same time as some other force.
A line cannot be concurrent. The concept of concurrency is normally applied to three or more lines in a plane or space.
