Brass is a substitutional alloy in which copper atoms in the host crystal are replaced by the similarly sized zinc atoms.

gold is an element so there is only one type of gold. you are probably wanting to know about gold alloys. Alloys are combinations of different metals. there are different types of gold alloys.
Ferrous alloys contain iron as the base metal, while non-ferrous alloys do not. Ferrous alloys are typically magnetic and have higher strength but lower corrosion resistance compared to non-ferrous alloys. Non-ferrous alloys, on the other hand, are lighter, have better corrosion resistance, and are often used in applications where magnetic properties are not desirable.

The term is applied frequently to iron and iron alloys.
Examples: stainless steels, zircalloys, amalgams.
In the medieval ages coins were made from either gold, silver or bronze. But none of them were alloys
Gold can form alloys with various metals, resulting in different types of gold alloys. Common metals used in gold alloys include copper, silver, zinc, and nickel. Each metal imparts its unique properties to the gold alloy, such as color, hardness, and durability.

The two types of alloys are substitutional alloys, where atoms of different elements substitute for each other in the crystal structure, and interstitial alloys, where smaller atoms fit into the spaces between the larger atoms in the crystal structure.
Sveral types depending on the car. Aluminium, steel alloys etc.
Both substitutional and interstitial alloys are types of solid solutions formed by combining two or more metals. In substitutional alloys, some of the host metal atoms are replaced by foreign atoms of similar size, while in interstitial alloys, smaller atoms occupy the spaces (interstices) between the host metal atoms. Both types of alloys can enhance properties such as strength, hardness, and corrosion resistance compared to their pure metal counterparts. Additionally, both types rely on the principles of atomic size and structure compatibility to achieve a homogenous mixture.
