My parquet floor is the typical shining type.  Does anyone know how make the parquet to be like in the pic(matt finishing)? What type of vanish does he use?
Any contractor to recommend?

Normally waterbased finishes can end up more matte than normal solvent based finish.

The picture you posted looks like 30% gloss level. Water based matte finish can go down to 15-20% gloss.

Doubt so. It need to be sand out.

Water based are better, scratch resistance (Well to me is more of less noticeable when scratch). Need to get the import type that usually use by floor timer.

You know where the Kuchai Lama KFC? opposite KFC have a row of shop. There is a shop doing wood flooring, they carry some water based sealer . Maybe you can go ask, not sure sell to walk in or not.

Don't think any contractor would be able to guaranty finish bonding performance if you don't sand out the existing solvent based finish if you plan on going with a new waterbased finish.

Wear depends on the finish used. Some wears better and stronger. Usually professional finish last quite a lot longer.
actually waterbased finish is usually a lot more expensive since they require more coats. It is normal to have minimum 3-4 coats. So there is the extra labour and material costs involved.
it really depends on the condition of the floor. If it has dents and deep scratches that need to be sanded out, it would be sanded out regardless of the finish you put on.
