things float in air because of density
Yes. For every fluid, there are things that float in it ... they just have to be things that are less dense than the fluid. That's how stones float in mercury, logs float in water, and hot balloons float in air.
Things that float in a fluid are less dense than the fluid. Things that sink in a fluid are more dense than the fluid.
Yes, in fact small things like bacteria, dust, etc. float in mid-air.
Freshwater is less dense than saltwater, and so it tends to float on top, as less dense things tend to float on denser things.
Whether or not you float has nothing to do with vacuum. You float because you are too far away from the earth (or other massive objects) for their gravity to have any noticeable effect on you. It just so happens that this occurs in space where natural vacuum may be found.
no
It is quite common for various things to float in water. But any liquid can cause things to float.
things float in air because of density
You can't make things float, things float by it's self's it's density is lower than 1 it can float, if it's density is greater than 1 it can't float.

Yes any salt can make things float
no it will not. because a balloon filled with hydrogen floats only because it is lighter than air so when there is a vacuum it will not float. it is like oil and water if there is no water oil is on the bottom if there is water it is on the top.
