Can we define "average velocity" as the possible and minimum velocity due to its proportion ?

This makes no sense.

The term "average velocity" has a clear and unambiguous definition in basic kinematics. If you want to use the same term, you have to follow THAT definition, not make up some of your definition.

Sorry to my mistake , actually i want to ask what if we say in different manner that average velocity is like the minimum and possible value due to its proportion.Am i understand it in right way ? (thanks and appreciate)

".... average velocity is like the minimum and possible value due to its proportion... "

I have no idea what you just said here.

Assuming that you know what is the definition of an average velocity, see if you can convince yourself with whatever it is you are trying to ask for by trying this problem:

A vehicle travels the first half of its journey with a constant velocity v1. It then travels the
second half of the journey at a constant velocity v2. What is its average velocity for the
whole journey?

Hint: It is not (v1+v2)/2.
