Yes.
a body is said to be at rest if it does not change its position relative to a reference frame similarly a body is said to be in motion if it changes its position relative to any reference frame.
Actually sitting on the earth we feel as if we are at rest. But relative to the pole star we are moving along a circular path. Also relative to the sun we are moving along an elliptical path around the sun. So actually speaking we are not at rest. In the same nothing is stationary. Everything is in motion. Rest means only a relative term.
Actually very difficult to determine, as the whole universe is in motion. One usually refers to relative rest or relative motion.
An object can be at rest relative to a second object whilst in motion relative to a third object.For example, if you sit still then relative to the Earth you are at rest. However the Earth is both spinning on its axis and travelling around the Sun, so relative to an observer in space you are in motion. Einstein showed us that all such concepts are relative.
At rest and in motion are relative terms. When we say 'in motion' or 'at rest' we mean relative to something else. If you were travelling in a car for instance, you would be at rest relative to the car but in motion relative to the outside world.

No. Motion and rest are only relative. The beauty is: The very space is relative. Time too is relative. Then which is the absolute? You are the absolute. The one who asks, the one who searches, the one who observes, is the absolute. But this becomes true only when one has Self Realization. Who am I? This is the valid query to be made by each and every one of us. All the best dear.

He is in motion relative to me, and he is at rest relative to his friends. There is no 'real' rest or 'real' motion. It's always measured relative to something else.
It's misleading to discuss those ideas because there are no such things as absolute motion or rest.

motion : when a body is moving or changing its position with respect to its surroundings is called motion. rest: when a body is not moving or fixed at a place with respect to its surroundings is called rest.
All motion is relative. The question "is this object moving?" is in fact meaningless unless we specify "moving relative to what other object". Similarly, there is no such thing as "absolute rest": it's just as true to say that the road is moving at 50 km/h relative to your car as it is to say that your car is moving at 50 km/h relative to the road.
