Air does not have a fixed composition. Its composition varies from place to place. Therefore it is a mixture.
CO It is not a mixture as you can't separate out the carbon from the oxygen as the two are joined. 
SnF2, which represents tin(II) fluoride, is a chemical compound, not a mixture. A compound is a type of molecule that is bound together with chemical bonds, while in a mixture, the different components are mixed together, but not bonded.
Distilled water is pure liquid H2O, which makes it a compound. It is not a mixture because it only contains one type of molecule.
