Zinc becomes plated with copper.
The nail will rust.
Nothing spectacular: a water solution of copper sulfate is obtained.
The solution will turn yellow
Formation of a copper sulfate solution in water. This solution has a herbicide and fungicide effect.
When Ammonia solution is added to Copper sulphate, at first a precipitate of Copper hydroxide is formed. If excess ammonia is added, finally a deep bluish solution of Tetraamine Copper(II) Sulfate is formed

The pH of a copper sulfate solution depends on its concentration. Typically, a 1% solution of copper sulfate has a pH of around 3-4, making it acidic.
It will darken the copper (II) sulfate solution.

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.
The iron which is a more electrochemically active metal gets plated with copper and iron sulfate is formed
Heating the saturated solution of Copper sulfate will not form the hydrated copper sulfate crystals because only after cooling down the saturated solution of copper sulfate then only the crystals of the hydrated copper sulfate can be formed
It isn't displaced as gold is less reactive than copper sulphate!
a copper sulfate solution it becomes copper (II) sulfate pentahydrate
