in case of a body kept on the surface of the earth does Normal reaction and weight makes action reaction pair?

Yes, according to Newton's third law of motion, a normal reaction and weight (action) makes an action reaction pair.
A body kept on the surface of the Earth exerts a downward force on the ground. The force exerted by the weight of the body is "action" and it acts on the Earth's surface whereas the force exerted by the Earth's surface on the body is "reaction" and it acts on the body. The "action" of the body acts on the Earth's surface and the "reaction" of the ground acts on the body. Thus action and reaction act on two different bodies.
