It contains only two elements. Fe shows +3 number. Chlorine shows -1 as the oxidation number.
The oxidation number of the overall compound is 0. The oxidation number of iron ions is +3. Chloride ions have -1 oxidation number.
Fe = 3+
Cl = 1-
for fe +2 for cl -1
For Mg the oxidation no is +2 while it is -2 for oxygen.

+2 for Mn and -1 for each Cl.
-2 for each O +6 for S
The oxidation number of Na in NaCl is +1, while the oxidation number of Cl in NaCl is -1.
No, it is not a redox reaction. None of the oxidation numbers changes during the reaction. You have to determine the oxidation number for each element and see if it changes from reactant side to product side. If the oxidation number doesn't change, it is not a redox reaction.
The hydrogen atoms are each in the 1+ oxidation state. The oxygen is in it's 2- oxidation state.
