No, air is matter and all matter takes up space therefore, having a mass. You can find it by subtracting the mass of the balloon from the total mass of the balloon and the air. (You will need a very accurate scale.)
Identify the weight of balloon with air. And identify the mass of the balloon. Now subtract the second from the first. You get the mass of the air present in it.
it's because of the ratio of the weight of the air in the balloon to the air outside the balloon

We are all similar to the experiment the scientist Galileo conducted when testing the laws of gravity. He had been atop the Leaning Tower Of Pisa and had thrown objects of the different weights and they had landed on the ground at the same time. This is because gravity pulls all objects, regardless of mass at the same speed. Some factors which could alter this could be air resistance, which causes friction. So if in a room without air, i think that the balloons will fall at the same time. Normally, though, i think that aside from some circumstances, the smaller balloon will fall first. (if there is air in the big one, of course it won't fall quickly, its mass will be reduced)
The mass of the balloon and its contents would be unchanged.

When the air mass is like the hot-air balloon =P
That depends on the ratio of the mass in the basket to the mass of the balloon. The bigger the carrying mass the greater the size of the balloon.
yes
Air, or oxygen and nitrogen is matter. All matter has mass. So the answer to this question is yes, air in a blown up balloon or any air does have mass.
depends on mass and if you include the air. same mass and not including the air they both weigh the same, air just expands the balloon and lowers the effect of gravity.
D: The hot air inside the balloon becomes less dense than the air outside the balloon.

Since air is matter, it does have mass. So adding its mass to the mass of the balloon would cause the balloon to have more mass. Weight is a measure of the pull of gravity on an object and an object with more mass is "pulled" more, so the balloon with air in it would indeed be heavier than a balloon without air.
When the air is heated inside the balloon, it expands, causing it to be lighter than the surrounding (and presumably) cooler air. One imagines however, that as the air inside the balloon is heated, some air is forced out (due to expansion), thus resulting in a decrease in the entire apparatus' overall mass (not to mention a decrease in mass due to any fuel's having been used to heat the air in the balloon).
