* Ricky: You can simply use the name "Ricky" as it is, as French people understand many foreign names.
* Richard: If you are looking for a more French-sounding name, you could use "Richard," which is the French equivalent of "Richard."
* Riccardo: Another option is "Riccardo," the Italian version of "Richard," which is also sometimes used in French.
Ultimately, the best choice depends on the specific situation and your preference.
