The ones to the left are Japanese mon coins from the 19th century. The two to the right are 100 mon: https://en.numista.com/catalogue/pieces11614.html
The one to the far left is different, haven't found that one.
The two coins at bottom right are probably not gold. They are Mexican fantasy coins, can be found on Ebay.
