Air. (Oxygen, Carbon Dioxide)
A solution that is composed completely of gas is carbon dioxide. Hydrogen dioxide is also a solution composed completely of gas.
For example a carbonated water containing carbon dioxide as a solute.
This scenario corresponds to Henry's law, which states that the solubility of a gas in a liquid is directly proportional to the pressure of the gas above the liquid. Therefore, by increasing the pressure of the gas, you can increase the amount of gas that dissolves in the solution.
There are a number of examples of solid in gas solutions, such as smoke, in which carbon and air are in the form of a solution. Automobile exhaust is another example of solid in gas solution. An example of such solution is Iodine vapors in the air.
An example of a solution where the solute and solvent are not easily distinguishable is a metal alloy, such as bronze. In bronze, copper is the solvent and tin is the solute, but they are completely mixed at the atomic level, resulting in a uniform composition throughout the mixture.
Air is an example of a gas-gas solution.
An example of a liquid-gas solution is carbonated water, where carbon dioxide gas dissolves in water. An example of a gas-gas solution is air, which is a mixture of various gases like nitrogen, oxygen, carbon dioxide, and others in the atmosphere.
Soda is an example of a liquid-gas solution, as it contains carbon dioxide (a gas) dissolved in water (a liquid).

An example of a solid and gas solution: hydrogen dissolved in palladium.
Gas in gas
gas-gas
A common example of a solid solution would be salt water. The salt (usually sodium chloride) is the solute and the water is the solvent. A common example of gas solution would be soda water (Seltzer or club soda). Soda water is a solution in which the gas, carbon dioxide, is the solute and water is the solvent.
When a liquid is dissolved in a gas, it results in a solution known as a liquid-gas solution or mist. The liquid particles become dispersed throughout the gas, creating a homogeneous mixture. An example of this is water vapor in air.
An example of a solid and gas solution: hydrogen dissolved in palladium.
A solution that is composed completely of gas is carbon dioxide. Hydrogen dioxide is also a solution composed completely of gas.
