This can happen if they move in opposite directions, and the sum of their momentum is zero. For example, before the collision one may have a momentum of 100 kg x meter / second to the right, and the other 100 kg x meter / second to the left. Thus, their total momentum before the collision would be zero; therefore this would be no problem from this point of view, since the total momentum after the collision is obviously also zero.
From the point of view of conservation of energy, mechanical energy is often lost in collisions; most of such energy is converted into heat energy.
Objects start moving when a force is applied to them, such as a push or pull. Objects stop moving when the forces acting on them become balanced, resulting in equilibrium. This can happen when an external force is removed or when other opposing forces come into play.
Because of friction, Friction is what causes moving objects to slow down and eventually stop. This is an important science idea we can use to describe the force that pushes back on a moving object and makes it slow down and stop.
Yes, two cars moving with the same velocity can collide if their paths intersect or if one fails to stop in time to avoid hitting the other. Velocity only describes the speed and direction of an object's motion, not its position. So, the cars can still collide if they have the same velocity.
Objects that are at rest have no kinetic energy. Additionally, objects that have come to a complete stop after moving previously also have no kinetic energy.
Without friction, moving objects will continue to move at a constant velocity in a straight line, as there would be no force to decelerate or stop them. These objects would essentially keep moving indefinitely unless acted upon by an external force.
They Bounce off of each other and then they stop
It is not only possible---it will stop moving at some point in the far distant future.

no
friction slows objects down but because of that it eventually brings them to a stop

no. not now at least. it is possible that it will in the future.
