Help with predicting products of single replacement reactions using the activity series (chemistry)

i get how to use the activity series to find out if it reacted or not, i just wanted to check answers on the ones i was confused about. (they all react, and the numbers are all subscripts)

Mg + Pb(NO3)2 --->
Cu + AgNO3 --->
Zn + HCl --->
Al + HCl --->

thank you so much!

Mg will replace Pb, both have +2 charge, so Mg(NO3)2 + Pb
Cu will replace Ag, Cu can be +1 or +2, but keep it simple, Ag + CuNO3
Zn will replace H, as will most metals in acid, H2+ ZnCl2
Al will replace H, so 3H2 + 2AlCl3
