The oldest signs — $ ¢ £ ¥ — are in ASCII and Latin-1 and work everywhere. Most others are in the Currency Symbols block, which grows whenever a country introduces a new sign. The “Added” column below matters: a sign added recently, such as ⃀ (som, 2021), is missing from many fonts and will show as a box on older systems.
Some signs are shared. ¥ is used for both the Japanese yen and the Chinese yuan; $ for dozens of dollars and pesos; ₨ is the generic rupee sign, while India has its own ₹ since 2010. Formatting — whether the sign goes before or after the number, and with what spacing — is a locale decision made by your number formatter, not by the character.
