AlCl3
Al2O3
Al2(SO4)3
Al2(CO3)3
Al(NO3)3
These are easy to determine if you look at periodic table and see Aluminum has three valence electrons. Chlorine is Cl -, oxide is O 2-, Sulfate is SO4 2-, Carbonate is CO3 2- and nitrate is NO3 -. So in order to balance the charges (give full valence shells) there would have to be three chlorines for each aluminum giving AlCl3, and so on.
You can do this for all of the (non-aluminum) compounds you asked about.

AlCl3=>aluminium chloride
Al2O3=>aluminium oxide
Al2(SO4)3=>aluminium sulphate
i dunno the formula of aluminium carbonate but that of aluminium carbide is Al4C3
Al(NO3)3=>aluminium nitrate
