A vector has both magnitude and direction. Does it mean that anything that has magnitude and direction is necessarily a vector? The rotation of a body can be specified by the direction of the axis of rotation and the angle of rotation about the axis. Does that make any rotation a vector?

No. finite rotation of a body about an axis is not a vector because finite rotations do not obey the laws of vector addition.
