Principal energy levels are an atom's major
energy levels, ranging in value from 1 to 7.
Energy sublevels are contained within principal
energy levels, and their number increases as the
value of the principal energy level increases.
In every atom there are principle energy levels, sub-levels and atomic orbitals. The principle energy levels are often those first taught when studying chemistry. They correspond to how close the electrons are to the nucleus. The first principle energy level is closest to the nucleus and can hold a maximum of two electrons. The second principle energy level is slightly further away from the nucleus and can hold a maximum of eight electrons. The third energy level is even further away and can hold a maximum of ten electrons. Each principle energy level is comprised of different sub-levels: s, p, d and f. The s sub-level can hold a maximum of two electrons; , p a maximum of 6; d, a maximum of 10 and f, a maximum of 14 (although the f sub-level is only present in the lanthanide and actanide series). Sub-levels all have different energies and electrons fill sub-levels in order of lowest energy to highest. The first principle energy level has one sub-level, the 1s sub-level. The second principle energy level has two sub-levels, 2s and 2p. The third principle energy level has three sub-levels, 3s 3p and 3d. (However, the 4s sub-level is filled before the 3d sub-level, which is a different matter which cannot be explained quite so simply.) Now, each sub-level is comprised of atomic orbitals which define the approximate boundaries of the electron orbit. Each orbital can hold up to two electrons, so a s sub-level has one orbital; a p sub-level has three orbitals; a d sub-level has five orbitals and a f sub-level has seven. This explanation is really quite brief as there is so much more information concerned with principle energy levels, sub-levels and atomic orbitals.
well when something is orbiting a planet that means an object is basically circling the planet due to its gravitational pull. Rotation is the planets rotation not the object surrounding circling it.

Any electron is not fixed to any sub-shell or orbital. If you provide sufficient energy to an electron, it would make transition to any of the higher energy orbitals and then come back to the lower orbitals radiating energy.
You can tell the difference between 2s sub-shell and 2p sub-shell by checking their energy levels whereby a 2p orbital has a higher energy level compared to a 2s orbital.

Sub energy pretty much explains itself: It is below energy level

They have many names. Common ones are orbitals or energy levels.

The range of the levels is between 0 to n-1. 3 minus 1 equals to 2, so we have 0, 1, 2 as sub levels. They are the same number of sub-levels.
The hydrogen atom has only one electron.
Sub shells or sub energy levels, s,p,d,f , they are represented by Azimuthal quantum number 'l'.
You can tell the difference between a 2s sub-shell and 2p sub-shell from their energy levels, because a 2p sub-shell is a higher energy level than a 2s sub-shell.
