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 being a vector, it is tricky to say that "velocity increases or decreases". Its magnitude might decrease - but its magnitude is, precisely, the speed.

When the magnitude of velocity increases, many people call that "speeding up".
what is magnitude of average velocity
It is called deceleration or slowing down.

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)
