There is gravity between all objects of mass, even between atoms.
So there is gravity between stars though its effect is very little due to the extreme distance between stars. The force of gravity between stars is so small they do not attract; however, the expansion of the universe is from the measurement of galaxies moving away from each other.
Galaxies also have gravity between them; however, it too is too small for attraction unless they get very close and collide.

The suns gravity has no effect on proxima Cen. we are not apart of any binary star system.
Proxima Cen. is apart of the alpha cen. triple star system where it orbits and is just coincidently the closest star to the sun.

Our sun is not revolving around proxima or Alpha centauri. It orbits the galactic center. Alpha centauri is closer to our sun than any other star, but it's still 4.3 light years from here.

gravity is there between everything and everything in the Universe..for example Gravity is there between u and me and me and the sun and me and Andromeda galaxy.
and sun and all other stars in Milky Way revolve around the galatic centre not any other star.
