if light could travel in vaccuum, and vaccuum is definitely not a matter, would u consider light is a matter?

The word matter is not well defined in physics. Usually light is not called matter, but light carries energy, which is equivalent to mass, so it's hard to enforce a distinction.
A vacuum has no matter in a way, but it is abuzz with all sorts of virtual particles of every kind that pop in and out of existence for very short periods of time (quantum field fluctuations). So in a sway, even a vacuum has matter.

Light is energy transformation and can travel trough vacuum. It is not a matter as has no rest mass.

Light is energy, not matter.
And being able to travel or exist in a vacuum in which no other matter exists doesn't mean it is, or isn't matter.

Totaly not, for something to be identified as a matter, it first needs to occupy space and have mass. Hence light is not matter.

There are particle for matter and energy
Light particle falls in the category of energy

It has been discovered that light is an electromegnatic wave as well as particles.
we belive that there are some small particles that make the light and we call them Photon.

Definitely not.
