Hydrogen - 1 valence electron
Sulfur - 6 valence electrons
Oxygen - 6 valence electrons
H+H+S+O+O+O+O = 1+1+6+6+6+6+6 = 32
You get the valence electrons from the roman numeral above each column in the Periodic Table.
Valency of Sulphar is 4.Valency of Oxygen is 2.

Things are complicated if we use the term valency. It is better to use the term Oxidation state or Oxidation Number. In SO2, the oxidation state of sulphur is +4 and In SO3, the oxidation state of sulphur is +6.
The valency of sulfur is 2.
SO2 - sulphur dioxide
You will get SO2 or sulphur dioxide, an acidic oxide
SO2

You don't say that. What you do say is that the valency of sulphur in sulphur trioxide is 6.
The valency of sulfur is 2.
