matter
I'm not sure what you mean by "resists change" but one word for something that takes up space and has mass is a substance.
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).
Yes, a vacuum is still a vacuum if electromagnetic waves are present. A vacuum is an area with no matter in it. We know that matter is anything which has mass and takes up space. Electromagnetic waves have no mass, and certianly take up no space. They're energy.
A mathematical point in space has no dimensions therefore takes up no space. Certain particles have no rest mass but have the energy equivalent because of the velocity they possess. A singularity is a theoretical no volume point but has a huge mass.
Neither have mass or take up space
Mass is defined as anything that has weight and takes up space.
matter
No. Matter is anything that has mass and takes up space (has volume). Energy has no mass and does not take up space, therefore it is not matter.

Mass
Anything with mass takes up space.
It is Energy; either this and/or empty space.
One object that takes up space and has mass is matter.Anything that takes up space and has mass is called matter in physics. This is anything that has physical substance.
Yes. To clarify: Solids : Take up a definite space and have defined shape Liquids : Take up a definite space but have no defined shape Gas : Have no defined space or shape.
There isn't a type of matter that doesn't occupy space, because matter is defined as having mass and taking up space. If it didn't take up space, it wouldn't be matter.

Anything that has mass and takes up space is matter. Energy is not matter because it does not have mass nor does it take up space. Pretty much everything else is matter.
