The correct classification of the reactions are as follows:
1) 2Mg(s) + O2(g)----> 2MgO (s)
It is a synthesis reaction or a combination reaction. It involves the bonding of the reactant molecules forming one single molecule with new set of properties.
2) Na(s) + Cl2(g)------> NaCl(s)
It is a combination reaction as well, the same as the first reaction.
3). PbCO3(s)------> PbO(s)+Co2(g)
It is a decomposition reaction where a single molecule is breaks down into multiple molecules.
4). Ch4(g) + 2O2(g)----> CO2(g) + 2H2O(g)
It is a combustion reaction since it involves the reaction with oxygen and the production od carbon dioxide and water.
