Hey MATE!
1) Aluminium atoms are small in size as compared to iron and copper therefore there are no gaps left for water molecules to enter in between the bonds of aluminium.
2) The greenish layer formed after rusting is [CuSO4.5H20] . It is nothing but the Copper sulphate in hydrated form known as Copper hydroxy sulphate.
Hope it helps
