It all depends of the alloy content.
Regardless of the fineness of the gold in the alloy, the allergy might be caused by the nickel content in that alloy.
The best is to ask in the jewelry store, prior to the purchase, if the golden jewelry contains any nickel.
White gold is one of the many alloys of gold. It contains at least one of nickel, manganese or palladium.

There is no copper in gold unless it has been intentionally added in an alloy. If you are referring to an alloy such as rose gold, the amount of copper would depend on the specific composition of the alloy.

Yes, silver and gold can be mixed to create an alloy called electrum. This alloy has been used historically for jewelry and currency. The proportions of silver and gold can vary, which affects the color and properties of the final alloy.
It depends on what color gold you are seeking. The two most common are white and yellow. White gold is an alloy of gold and either nickel, palladium, silver, or manganese. Some people are allergic to nickel, so make sure you know what your jewelry is alloyed with. Yellow gold is generally a mixture of gold and copper. Blue gold is an alloy of gold and indium. Purple is gold and aluminum. Rose gold cannot be 14K because in order to make gold reddish, it has to be mostly copper.
The main component of 16 karat gold alloy is gold, which is typically mixed or alloyed with other metals such as copper, silver, or zinc. These additional metals are added to increase the hardness and durability of the gold alloy while maintaining its desirable gold color.
