The sulfur in potash alum occurs in sulfate ions, which have the formula SO4-2. Since sulfur is less electronegative than oxygen, the oxygen has an oxidation number of -2; 4 atoms of oxygen give a total negative charge of -8, and the sulfur atom must have an oxidation number of +6 to match the -2 charge of the sulfate ion as a whole.
The oxidation state of aluminium in potash alum is 3

An alum stone is a subsulphate of alumina and potash - also known as alunite.
Potash alum is another name for potassium alum. Alum is a class of molecular compounds, and included in the class is potassium alum. So, they are not the same thing, but yet very similar in that potash alum is a member of the alum class.
Potash alum has the effect of a poison on the body. It has been linked to the incidence of Alzheimer's disease in people who have used it as a deodorant.
