There isn't a particular name, however, when they are moving towards us, their spectrum is shifted to the blue region.
So they are referred to as blue shifted galaxies but that is only relative to ourselves.
See related link for more information.
Galaxies moving toward each other at different speeds are called interacting galaxies. These interactions can result in tidal forces, collisions, and merging of the galaxies, leading to various changes in their structures.

Yes, some of the galaxies are moving toward each other like our milky way and Andromeda moving toward each other with the speed 120 km per second and after 3 billion years from now these galaxies collide with one another. The current distance of Andromeda from milky way is about 2.5 million light years
Most galixies are micing away from each other, at a constantly accelerating pace as time passes.
No.More specifically:Not all galaxies are moving away from each other. The Milky Way and Andromeda galaxies are moving towards each other (and at a pretty good clip, too: about 300 km/s). The entire "local group" of galaxies is moving in the general direction of something called the "Shapley Supercluster".Very distant galaxies do tend to be moving away from each other, but that means the universe is expanding, not contracting.
all volcanoes are caused by the earths plates moving toward each other and that is called convergent boundaries.
Galaxies in the expanding universe are moving away from each other at speeds proportional to their distance, with more distant galaxies moving faster. This phenomenon is known as the expansion of the universe.
Other galaxies are moving away because the universe is expanding, but we are not at the centre of the universe.
Galaxies are moving away from each other in a constantly expanding universe
Not all galaxies are moving away from each other. In fact the galaxy Andromeda is moving toward the Milky Way and they will eventually collide, because Andromeda is so much bigger than our Milky Way it will preatty much eat us and ruin our galaxy. Good news: it won't happen in our life time, and we are the 2nd largest gallaxy in the Local Group and no other (known) gallaxies are moving toward us.
No. A redshift means that the light has lost energy; one way for this to happens is if galaxies or other objects moveaway from us.
Red shift indicates that other galaxies are moving away from us, implying that the universe is expanding. This phenomenon is a key piece of evidence supporting the Big Bang theory. The amount of red shift is used to determine the distance and speed at which other galaxies are moving relative to us.
