There are four types of quantum numbers. The principle quantum number tells you which energy level the electron is in. The Orbital (can also be called azimuthal or angular) quantum number tells which sublevel the electron is in, like s, p, d, or f. The Magnetic quantum number tells which orbital the electron is is. s only has on orbital for it will have only one magnetic quantm number. p will have 3 numbers because it has 3 orbitals. d will have 5. f will have 7. The spin quantum doesn't relly matter if it is positive or negative. but when the principle, orbital, and magnetics are the same they have to have different spins.

You can speak of a spin 'n' particle, where n is a positive number; an integer or half-integer in the case of standard particles (ie. not quarks etc, but electrons, photons etc).
The spin that you measure a particle having is going to be a whole number difference from the particle's "generic" spin, between + and - that spin. So an electron, being a half-spin particle, will have +/-1/2 spin, whereas a photon (a spin 1 particle) will have a spin of 1, 0, or -1. An electron pair (to be found in superconductors) will have the same range of spins as a photon. A molecule will have the maximum spin of the total of its component's spins.
When ever you measure the spin of a particle, you will always get a value a whole number difference from the maximum, between +/- maximum value. This happens whatever angle you measure at, where the angle in which an entangled particle has been measured simply affects the probability distribution of the measured spin of the current particle at different angles. You can't get an inbetween value by measuring "halfway".
I can't remember how magnetism works, so I'll have to skip that part of the question.

Quantum numbers are four parameters which are used in deriving a particle's wave function. The magnetic quantum number is closely related to a particle's angular momentum directional vector.
Spin number isn't a concept which can be grasped physically since it doesn't related specifically to "spin." However, spin number is decided by when the electron is assigned to a subshell orbital. All oribitals must be filled with a positive spin electron (1/2) before any can be filled with a negative spin electron (-1/2).

Quantum numbers crash course.
n
Refers to the shell of the electron we're dealing with, i.e. the first, second, third etc. layer of electrons
l
Refers to the type of orbital. When l=0, it's an s orbital. l=1 is a p. l=2 is a d. And so on.
ml
Refers to the specific orbital. For example, an atom has three p orbitals. Each is designated by a different value of ml.
ms
Refers to the spin of the electron. By the Pauli exclusion principle, you can't have two electrons of the same spin in one orbital. The value, in your case, is arbitrary. The importance comes out in comparing electrons. In that case, you need to know if they're the same or different.

dude,question z somewhat exciting,as u requested y v take -a million/2 and a million/2 ,the only answer iz as v ol be attentive to electrons revolves in 2 guidelines,clockwise and anti clockwise..,so as v have already used all da crucial values in designating different quantum nos. so datz y v have left up wid in basic terms irational nos.

The spin can be either 1/2 or -1/2, because there are 2 possible electrons. As far as I know it isn't one or the other...
Remember: uncertainty principle: you can't know where an electron is and where it's going at the same time.
