The air you breathe is a gas which is one of the four physical states of matter.
To fill your lungs by sucking in air.
Matter has weight and takes up space. You know that air takes up space, because when you breath in, your lungs fill with air and expand. :) MoMMy.!
Yes, air is an example of a fluid. Fluids are substances that can flow and take the shape of their container, and air fits this definition.
Yes. Matter is anything that exists. On earth, it is very difficult to NOT have something that is a sample of some kind of matter. Air is a mixture of transparent gases, but it has pressure and weight and mass; thus, it is matter. Unless a container is a perfect vacuum (such as you'd find in interstellar space, or a science laboratory with complicated equipment for artificially creating one) it contains matter.
A smell is indeed matter, it is small invisible chemicals dissolved in the air that your nose is able to detect when these molecules land on them as you breath (sniff) the air.
Air consists of a variety of different gases in relative proportions. Air is composed of oxygen, nitrogen, carbon dioxide, methane, and other elements and compounds. These elements and compounds have a mass and they take up space. Matter is defined as anything that has mass and takes up space (matter has a mass and volume). Air is matter because it fits the definition of matter (based on its properties and how we currently think about matter).

Its breath of fresh air.

Air is certainly matter; air has mass, has takes up volume. I am not sure that the definition you give is one scientists would use; we would more likely say matter has properties of mass, volume and can be detected by appropriate instruments.
because water is how they breath and air is how we breath. we cannot breath in water so they cannot breath in air.
Yes. All humans breath a type of air called oxygen. Without oxygen we would die.
