Hydrogen
Helium, neon, and argon are the three lightest members of the noble gases.
The first four are (in order of increasing number / mass: He = Helium, Ne = Neon, Ar = Argon, Kr = Krypton Xe = Xenon and Ra = Radon are the other two noble gases
All of the group 8 (group 0) elements - Helium, Neon, Argon, Krypton, Xenon, Radon
Hydrogen is the most chemically reactive among the elements listed. It readily reacts with other elements to form compounds, while helium, argon, and neon are inert gases and generally do not undergo chemical reactions under normal conditions.
Im guessing by gas non-metal, you mean the non-reactive noble gases. These are: Helium, Neon, Argon, Krypton, Xenon and Radon

Hydrogen, Helium, Neon, Argon, Krypton, Xenon, and Radon are the noble gases. Im not sure if there are more.
Helium, Neon, Argon and if another Krypton.
HELIUM,NEON,ARGON,KRYPTON,XENON and RADON are the noble gases
