    CO₂, we would be dead

    He, we would be ok, but plant life would eventually die, as they need nitrogen. Ditto with other noble gases.

    H₂, that would be an explosive mixture and the entire atmosphere would explode, killing all life.

    Methane, also explosive.

    It depends on which gas. Nitrogen is not poisonous, but many others are.
