No, gold is less reactive than copper.
When gold is dipped into a solution of copper sulfate, a redox reaction occurs where copper ions in the solution gain electrons and are reduced to solid copper metal. The gold does not react and remains unchanged in the solution.
At STP, there will be no reaction. Gold is much less active than copper so there will be negligible gold sulfate formed by substitution. Gold is the lowest metal in the electrochemical series, so it will not react chemically with salts of any other metal.
Adding zinc to copper sulfate will result in a displacement reaction that will create copper metal to precipitate as a solid. CuSO4(aq) + Zn(s) ---> ZnSO4 + Cu(s) This reaction is quite exothermic too, meaning it will give off alot of heat - enough to make it too hot to hold the reaction beaker in bare hands.
Zinc is the metal that will replace iron in an iron solution through a displacement reaction because it is more reactive. Copper, gold, and lead are less reactive than iron and would not displace it in a solution.
Yes, zinc can displace copper from gold chloride solution through a redox reaction. The zinc will react with the copper ions in the gold chloride solution, leading to the formation of copper metal and zinc chloride.
Copper, silver, and gold are three safe examples.

Metals like gold, platinum, and silver typically do not react with copper sulfate. Additionally, metal compounds that are less reactive than copper, such as zinc oxide or aluminum oxide, will not react with copper sulfate either.

When a gold ring is dropped into a solution of copper nitrate, a redox reaction takes place where the gold would dissolve as gold ions, and copper from the copper nitrate would deposit onto the ring. This results in the gold ring becoming plated with a layer of copper.
to replace copper with gold
Silver is lower in the reactivity series than Zinc and therfore cannot displace the Sulphate from the Zinc. But on the other hand zinc is higher than copper, and when displacing the sulphate from the copper it changes colour due to the reaction.

Copper into gold, means putting copper powder in gold salt solution. Because copper is closer to hydrogen then gold, in the electromotive scale, it will dissolve, freeing the gold
