Wind has mass, but not too much of weight (weight = mass x gravity). Gravity can pull down objects with weight, not objects with mass alone.

Anything is matter besides space or anti-matter.
So air is matter as well. And wind is nothing but moving air.
Therefore wind underlies the rules of gravity and is indeed "pulled down". Otherwise it would, together with the entire atmosphere, be stripped off the earth by centrifugal forces of its own rotation and rotational speed around the sun.
Of course, air isn't as dense as e.g. rock or water, that's why it won't be ''pulled down" to the bare ground.
And the centrifugal force of earth's own rotation is one reason why wind occurs at all, besides area temperature differences.

Wind has no mass...air does have a mass and it is held down by gravity...that's why we have an atmosphere! The wind is formed by differential heating of the earth's surface and atmosphere causing changes in pressure. Where the pressure is higher the air moves away towards areas of lower pressure, which we feel as wind.

It does, it is what keeps the atmosphere "stuck" around the earth and keeps it from floating out into space..although we do loose a few light molecules around the thermopause occasionally.
Because it's a gas, it's less dense than solids or liquids..so it's above the earth and ocean that are heavier. The wind is kind of like a bucket of water that's been stirred..it moves, but it's staying in it's "bucket" close to the surface of the earth. Like the water in the bucket..each water molecule can not be at the very bottom of the bucket..some have to be at the top and if the bucket moves or spins.. (like the earth does) the water will move around without really going anywhere.

because wind has negligible weight. actually it has a mass and weight. its not true that wind has no weight for whatever that has mass has weight too. If we can just see the wind with our eyes then we can see it going down too in a fair weather.

because it has enough escape velocity? the gravity isn't really that strong

think you need to learn how to ask question right.
