Flammable gas will burn. Toxic gas is poisonous. A gas can be toxic, but not flammable, flammable but not toxic, both, or neither.
no
Carbon monoxide is both toxic and flammable.
Helium is the lighter gas but hydrogen is very flammable
Propane is C3H8 and natural gas is (mostly) methane, which is CH4. They are similar in that they are both saturated hydrocarbons that are extremely flammable and commonly used as fuels, but they are two different molecules.
Yes. Natural gas is composed of mostly of methane (which is flammable), as well as lesser amounts of other flammable hydrocarbons. ** Actually, natural gas is not flammable on it's own and must mix with air to be flammable.
Both flammable and combustible mean apt to burn.
no
Phosphine is a toxic and highly flammable gas.
Carbon monoxide is both toxic and flammable.
Helium is the lighter gas but hydrogen is very flammable
It is extremely flammable and toxic to your skin or lungs.
A colorless,odorless toxic flammable gas formed incomplete combustion of carbon

Capable of igniting and burning is a combustible gas. Any compressed gas meeting the requirements for lower flammability limit, flammability limit range, flame projection,etc. All flammable substances are surely combustible, but all combustible substances are not essentially flammable.
Class 2 gas only means it's compressed and includes flammable/combustible, poisonous and inert (non-flammable, non-toxic) gases. You would only need a fire extinguisher for flammable gas, which is Class B.
Neon is perfectly safe; it is an inert gas, which is therefore neither toxic nor flammable.
