The principal quantum number for the highest energy electron in carbon would be 2. It is easy to spot this, since carbon exists in row 2 of the period table. The row in which an element resides always shows the highest value of n, or the principal quantum number, that an electron can reside in.

There is no single quantum number that will tell you the size of an atom.The best answer to the question is the principal quantum number n, though it isn't a particularly good answer. While in general atoms with high maximum n tend to be larger than atoms with low maximum n, this doesn't always hold true. For example, chlorine (highest n value 3) is actually slightly smaller than lithium (highest n value 2).Also, two atoms with the same maximum n can be significantly different in size.
An electron configuration shows the distribution of electrons among the subshells. Each number shows the principal quantum number, or shell, the subshell and finally the orbital of the electron.
A Schrodinger atomic model doesn't exist; you think probable to quantum mechanics.
The atomic states with principal quantum number 4 can have orbital angular momentum quantum numbers from -4 to 4. Hence there are 9 possible values of the orbital angular momentum quantum number. Each electron can have spin +1/2 or -1/2, so each of the states specified by a given orbital angular momentum quantum number can have at most two electrons in the state without violating Pauli's exclusion principle. So, in sum, there are 18 possible states for an electron with principal quantum number 4.

s p d f are spectral lines sharp, principal, diffuse and fine seen in atomic emission spectra. These are also letters assigned to atomic orbitals which are defined by the azimuthal quantum number l which in turn is related to the principal quantum number n. These are sometimes referred to as sub-shells. K, L, M, N are another name for the electron shells defined by the principal quantum number n. K is 1, L is 2 etc.
The principal quantum number is the level of the most energetic electrons in an atom. It also corresponds to which period the element is in on the periodic table. For example, barium has a principal quantum number of 6 because its valence electrons are in level 6, and the element is in period 6.

I think you are referring to the 3 quantum numbers, n, l m; principal azimuthal and magnetic. Together with the spin quantum number they "define" an electron- but I would hesitate to call this the electrons location- Heisenbergs uncertainty principle gets in the way of a simultaneous knowledge of energy and location.
The atomic radius of elements increases as you go down a group. This increase in radius as you go down a period is primarily caused by the increasing principal quantum number of the outer electron shells.
They're called atomic orbitals, and are explained through the use of quantum mechanics.
