Noble gases are gases and have completely filled orbitals / energy levels. They generally have 8 valence electrons (helium has only 2) and have stable electronic configuration. Hence they are chemically inert and generally donot form compounds under normal conditions.
Noble gases are all monatomic (single-atom molecules) and have the following characteristics under normal conditions :

They are "unreactive" as their outer electron shells are full and thus will not donate or accept electrons readily.
Examples: XeF2, XeO3, XeOF2.
Noble gases do not react chemically with other noble gases.
No, not all noble gases have at least 3 electron shielding layers. The noble gas helium (He) has only two electron shielding layers, while the remaining noble gases (Neon, Argon, Krypton, Xenon, and Radon) have three or more electron shielding layers.

Argon share most characteristics with neon.Both are noble gases on above the other.
No. The first three noble gases (helium, neon and argon) have 1, 2 and 3 energy levels respectively.
Examples: XeF2, XeO3, XeOF2.
Noble gases do not normally form compounds.

The Group 18 elements are called the noble gases or sometimes inert gases. Wikipedia has information on the noble gases, and a link is provided.
