Note that Mohamed shows legend() being called before figure(2) is called.
It is possible to add a legend to an axes that is not the "current" axes, but it requires finding the handle to the axes.

You need to make the x and y data separately, like this:
figure(1)
plot(x,P1)
hold on
plot(x,P2)
plot(x,P3)
plot(x,TotalDemand)
plot(x,TotalSupply)
hold off
legend('P1','P2','P3','TotalDemand','TotalSupply')
figure(2)
stairs(x,P1)
hold on
stairs(x,P2)
stairs(x,P3)
hold off
legend('P1','P2','P3')
figure(3)
stairs(TotalDemand)
hold on
stairs(TotalSupply)
stairs(Ene_Unserved)
hold off
legend('TotalDemand','TotalSupply','Ene_Unserved')
