It can be a any group. Generally they shows +2 in group 2.
+2 for group 2 elements
Hydrogen has -1 and +1 oxidation numbers. Other elements have +1 only
Because there in group 2
Group 1 elements have +1 oxidation number (except for hydrogen) All group 2 elements have +2 oxidation number Fluoride ion always has -1
They do not. The group 2 elements, Be, Mg, Ca etc, have oxidation numbers of +2.

Because there in group 2
Magnesium is in the group 2. 0 is the lowest oxidation number for it.
Group 2 or alkaline earth metals
0- any element by itself has an oxidation number of 0.
Group 1 or alkali metals (+1 oxidation number). Group 2 or alkaline earth metals (+2 oxidation number).
Elements in group 2 mostly takes the oxidation number +II.
Strontium is in the second group. It shows only +2 number.
