It starts a reaction
Nothing will happen. Displacement reaction only happens when the element is more reactive than the salt solution. An example will be the otherwise. If you put aluminum metal into a solution of Copper (II) Sulfate. The aluminum metal will displace copper metal and you will have a solution of Aluminum Sulfate and copper metal. As long the element you put into the salt solution is more reactive than the cation of the solution, it will displace the metal.
Nothing. Copper is lower than iron in the electromotive series and will not replace the iron in the iron nitrate solution.
no reaction would take place
The iron which is a more electrochemically active metal gets plated with copper and iron sulfate is formed
When Iron metal is dipped into a solution of copper sulfate a REDOX reaction occurs in which the Copper is reduced (gains electrons) and the iron is oxidised (loses electrons). When this happens, the iron metal becomes iron ions and the copper ions in the solution become copper metal. Cu2+(aq) + 2e- --> Cu(s) Fe(s) -->Fe2+(aq) + 2e- This occurs because the iron is a more active metal than copper, and as a general rule of thumb, a more reactive metal will displace a less reactive metal from solution. This principle underlies the action of the sacrificial electrode.
The nail will rust.
It forms a brown ring just above the copper solution.
Formation of a copper sulfate solution in water. This solution has a herbicide and fungicide effect.
the solution turns green and the nails develop a brown deposit which is copper. the iron displaces the copper in the copper sulphate solution. This is because iron is more reactive than copper.
A chemical reaction.
Nothing
The solution will turn yellow

Nothing spectacular: a water solution of copper sulfate is obtained.
Zinc becomes plated with copper.
Any reaction occur.
Silver crystallizes on the surface of the copper as it gets absorbed into the water
