Yes it can be!!!
If two cars on a straight road head directly toward each other at a speed of 60mph (relative to the road), the velocity of one relative to the other is 120mph.
This example arbitrarily uses the road as the reference for each car's speed, but there really is no such thing as "absolute velocity" and both cars would have a velocity of about 1000mph relative to the center of the Earth.
According to Einstein's principles of "Relativity" all velocity is relative.
If the velocities are equal from my point of view, then I see them both moving at the same speed and in the same direction. That means that from the point of view of an observer riding on either body, the other one is standing still. Their relative velocity is zero. This is exactly the situation with a passenger and the book she's reading, both in an airliner flying west at 400 mph.
Sliding friction is always less than the static friction by small amount.
In exercise physiology, the difference between absolute and relative expressions of anaerobic power is that absolute mean power is calculated using the constant rate of falling bodies while relative mean power is calculated using a person's body weight to be able to compare power produced by that individual to their own body weight.
There are several layers of complexity to resultant velocity of a colision based on the assumptions used. In a cohessive colision, two or more bodies colide and fuse into one. The resultant velocity is the speed and direction the new body will travel due to the momentum of the original bodies. In a non-cohessive colision, two or more bodies colide, but subsequently rebound away from each other based on the area of contact and momentum of the relevant bodies. The resultant velocities are the speed, direction, and rotation the bodies after the crash.
The velocity of free falling bodies does change due to gravity accelerating them towards the ground. However, in the absence of air resistance, the acceleration due to gravity causes the velocity to increase at a constant rate, resulting in a uniform change in speed over time. This creates the perception that the velocity is not changing, but in reality, it is increasing continuously.
For two bodies with equal radius, the more massive has the greater escape velocity. For two bodies with equal mass, the one with smaller radius has the greater escape velocity. Both conditions listed in the question indicate greaterescape velocity.

The increased damage when two bodies collide head-on is due to the momentum of the objects, which is the product of their mass and velocity. When two bodies collide from opposite directions, their momentums add up, resulting in a greater force of impact compared to collisions at other angles where momentums may partially cancel out.

when two bodies change their positions with time, it's termed as motion and if the motion continues it may begin to have velocity,acceleration etc
Yes.
Because long, thin bodies, presenting a greater surface area relative to volume, are better able to dissipate body heat respect to rounder bodies that instead are better suited to preserve body heat. The round bodies of the Inuit of the Arctic and the tall, slim bodies of some African population are examples of natural selection at work.

Celestial bodies with mass are gravitationally bound because the gravitational force between them is strong enough to keep them in orbit around each other. This force is determined by the mass of the bodies and the distance between them, as described by Newton's law of universal gravitation. As long as the gravitational force is greater than the escape velocity, the bodies will remain bound to each other.
