Methane gas is a significant green house gas that contributes to global warming.
If your question is "Is natural gas often found where crude oil is found?" then the answer is yes.
In gas field in form of gas........
Natural gas is a gas.

Neon gas is found in very minute quantities in our atmosphere. It occurs 1 part in 65,000 (by volume) or 1 part in 83,000 by mass.

Yes, ozone is found in trace quantities in earth's atmosphere. it is a greenhouse gas.
propane Yes, to propane if the gas cooker is fueld from bottled gas, but if it uses natural gas then Natural gas is a gaseous fossil fuel consisting primarily of methane but including significant quantities of ethane, propane, butane, and pentane. I believe it also has a smelly agent added so that one can smell a gas leak.
We can make xenon (and we do in nuclear reactors - but not on purpose). But this inert or noble gas is found in the atmosphere in very small quantities (trace amounts). A link can be found below.
Volume
Yes; unimagineably huge quantities of it.

Nitrogen is a fairly inert gas that has no harmful affects unless it is found in too high of quantities. This would cause oxygen deprivation. It would be a bad idea to enter a pure nitrogen environment.
The chemical breakdown of enormous quantities of organic material buried in the sedimentary rocks has produced ethane gas.
