The book says..bodies experience mutual gravitational
attraction with each particle of the earth...

In the picture.... the vector from the apple pointing to the center of the earth.. is that the attractive force of by the earth attracting the apple?

and what about the vector pointing from the earth in the upward direction... is that the attractive force created by the apple attracting the earth?

Yes. And the force are each drawn from the centre of mass, since they are not contact forces, so there is not point of contact to draw the forces from/at.
