Cu + CuSO4 -> ???

It can't displace itself.

Group I and II elements always react with water. So do oxides e.g. SO2 + H2O -> H2SO3; MgO + H2O -> Mg(OH)2. However reactions with water are even more ambiguous than oxygen as water isn't as chemically reactive as oxygen.

Oxygen reacts with almost everything on the periodic table. Even freaking Xenon which is a noble gas.

Like for example lead and water have no reaction, but how can u tell from looking straight from the table
In general there's no way to work these out purely by logic. Scientists observe what happens and record these observations. So you basically need to memorise the chemical reactions, as they are just the way nature is rather than something that can be deduced purely by logic (generally speaking).

How could noble gases ever react??

They have a full electron configuration so why would they react?

Noble gases can react under extreme conditions - usually very high temperature and an extremely electronegative reactant (eg. oxygen/fluorine) are required

I know that, but the circumstances here arent what you said...
