No no, dissolution does generate (sometimes negative) heat. It’s called heat of solvation and it exists because when something dissolves it breaks solute-solute bonds, requiring energy, but then forms solute-solvent bonds, releasing energy. This difference can either result in the solution becoming hotter or colder than its components.
Okay this is apparently one of those things where you’ll get different answers depending on who you ask (even different Wikipedia articles give different answers), but this is a matter of semantics. No matter what you call it, mixing on a molecular level will result in the release or absorption of (in the case of gases a very small amount of) heat.
The edge cases, so mixing very polar with very nonpolar gases has deviations in enthalpy. Very tiny, but they exist.
Mixing inert species like nitrogen, CH4 or oxygen (anything human, fart or air related) does not result in a change in enthalpy. All it does is increase entropy. They are essentially ideal gases under these conditions, nothing happens.
Which Wikipedia article? Please name them so they can be corrected.
Heat does not get absorbed. Semantics or not, these words have well defined meanings.

This is not happening here. There is no solution, everything is a gas.
Yeah solutions can have any phase of solute and any phase of solvent. The most common example of a solution of gases is the air, so yeah.
No. Gas in gas can not be a solution. The solvent must be a solid or liquid.
