How can the force of gravity of the Earth be constant in relation to various objects that have different masses thus different gravity forces of their own?
It can't.
However, the mass of the Earth is (obviously) much greater than that of any object in it's surface. Thus, the gravitational effect of the object on the Earth is not relevant (unless you're really into very small numbers) and you can talk, for practical purposes, of a gravitational constant.
