A decrease in magnitude is typically referred to as a decrease in intensity or amplitude. A decrease in velocity is commonly described simply as slowing down.
It is called deceleration or slowing down.
The decrease in magnitude velocity refers to the reduction in the speed of an object or particle. It indicates the change in the object's velocity moving towards a slower speed.
An increase in the magnitude of velocity is called acceleration. It refers to the rate at which an object's velocity changes over time.
It is called acceleration.
An object that decreases its speed also decreases the magnitude of its velocity and decreases the magnitude of its momentum. Momentum is mass time velocity. Less velocity, less momentum. Technically, velocity is a vector and therefor momentum is a vector. One can speak of smaller or larger magnitudes of a vector, but not smaller and larger vectors because vectors have magnitude and direction. Speed is the magnitude of velocity.

what is magnitude of average velocity
Yes, it is possible for speed to increase while velocity decreases if the direction of velocity changes. For example, if an object is moving in a circle, its velocity (speed and direction) changes constantly while its speed can increase or decrease depending on the acceleration.
Any change of velocity, including a decrease of speed, is described and measured as acceleration. Assuming the velocity and acceleration vectors point in the same direction, then in the case of decreasing speed, the magnitude of the acceleration is a negative value. Negative acceleration is often called deceleration, but that is just a special case of acceleration.
Velocity is a vector , which it means it has both magnitude and direction. Scalars have only magnitude. The magnitude of a velocity vector is usually called speed . Although I have never heard it called by that name, scalar velocity is speed.
Velocity has a DIRECTION as well as a MAGNITUDE (that is, velocity is a VECTOR quantity if you've learnt that term yet) The magnitude of velocity is called SPEED (just a POSITIVE number/scalar, not a vector)
