"Noble gas configuration" means that in writing out an electron configuration for an atom, rather than writing out the occupation of each and every orbital specifically, you instead lump all of the core electrons together and designate it with the symbol of the corresponding noble gas on the Periodic Table (in brackets).
For example, the noble gas configuration of phosphorus will be [Ne]3s23p3
Noble Gas Configurations
The externall shell of electrons is completely filled.
Pseudo noble gas configurations for cations are achieved by removing electrons from the highest energy levels first. For example, for the cation Na+, the electron configuration can be represented as [Ne]3s1, where Ne represents the noble gas neon. This notation helps to show the remaining electrons in a shortened manner.
The externall shell of electrons is completely filled.
They achieve noble gas configuration by the sharing of electrons.

None of the noble gases have 5 sublevels. All noble gases have electron configurations that end in an s or p sublevel.
Atoms achieve noble gas configurations in single covalent bonds by sharing electrons between them, forming a stable electron configuration similar to a noble gas. This sharing allows both atoms to attain a full outer shell of electrons, satisfying the octet rule.
In noble gas notation, you don't have to write the electron configuration up to that noble gas. You simply put the noble gas in brackets [noble gas] and then continue to write the electron configuration from that point. It just makes it shorter and easier to write electron configurations for elements with a lot of electrons.
Although the formation of an octet is the most stable electron configuration, other electron configurations provide stability. These relatively stable electron arrangements are referred to a pseudo-noble gas configuration. Although the formation of an octet is the most stable electron configuration, other electron configurations provide stability. These relatively stable electron arrangements are referred to a pseudo-noble gas configuration.
Na, Rb, Al3+, and S2- do not have a noble gas configuration as they do not have the complete outer shell of electrons like a noble gas. O2, Br, Ca, and O2- have noble gas configurations as they either have a complete outer shell of electrons or have gained/lost electrons to achieve a stable noble gas configuration.
Transition metals, lanthanides, and actinides do not typically have a noble gas electron configuration due to the presence of partially filled d or f orbitals. These elements have unique electron configurations that differ from the stable octet or duet configurations of noble gases.
