No. Oxidation number is the same as oxidation state.
NO!!! Phosphates it is '+5' Phosphides it is '-3'
The oxidation number of any monoatomic ion is equal to the charge of the ion. For example, the oxidation number of the sodium ion (Na+) is +1, and the oxidation number of the chloride ion (Cl-) is -1.
The oxidation number of monoatomic ions is the same as their ion charge: +2 in Fe(II) for Fe2+, +3 in Fe(III) for Fe3+, -2 in sulfide S2-
Fluorine: -1 Chlorine: -1, +1, +3, +5, +7 Bromine: -1, +1, +3, +5, +7 Iodine: -1, +1, +3, +5, +7 The normal oxidation state of halides is -1, but with, for example, chlorine other oxidation states exist. Hypochlorites (+1), Chlorites (+3), Chlorates (+5), Perchlorates (+7). The same is true for all halogens, with the exception of fluorine, that seems to like it's -1 status and won't form fluorates.
the oxidation number of each K is +1. But there are two K's so 1*2 is +2. the charge on the molecule has to equal 0, so the oxidation number of the S must be -2.

Sometimes yes ... sometimes no. Valency of chlorine is 7 ... it has 7 valence electrons. But its most common oxidation number is -1.

There is at least one oxidation number shared by all the elements in a periodic table column, but some of the elements may have more than one oxidation number and some of these additional oxidation numbers may not be possible for all the elements in a column.
'Oxidation number' and oxidation state are often used interchangeably. Oxidation state is a formal way of determining the degree of oxidation of an atom or ion or molecule; for ions the oxidation number is equal to the ionic charge. In non ionic compounds the most electronegative element is assumed to "own" the electrons. So in say InP which is a semiconductor and not ionic, the oxidation state of indium is +III and P is -III. Oxidation number is a convention used in complexes. Ligands are removed from the ion with all bonding electrons. Often the oxidation number and oxidation state have the same values but calculating the the oxidation number of N in ammonia, H is removed as hydride ion, H- you get the strange looking result of nitrogen with an oxidation number of +3. In contrast the oxidation states of N and H would be calculated as -III and +1

Phosphorus increases its oxidation number in this reaction. In H3PO4, phosphorus has an oxidation number of +5, and in K3PO4, it has an oxidation number of +5 as well. This means that phosphorus's oxidation state remains the same throughout the reaction.
The element which has the same oxidation number in all of its known compounds is fluorine. Fluorine always has an oxidation number of -1 in its compounds because it is the most electronegative element.
An element's most likely oxidation state is often related to its number of valence electrons. The oxidation state is typically the charge an atom assumes when it forms ions, and it tends to be the same as the number of valence electrons the atom gains or loses to achieve a stable electron configuration.
