Normal reaction is the force acting between two contact surfaces. Like, if you push a wall, you will feel an opposite force acting on your hands. That''s normal reaction.
You can find it by Newtons third law, action and reaction are equal. For example, if a block of 2 kg is lying on a table, it exerts a force of 20N (Mg) on the table, thus the normal reaction is also 20N
