How many different Yoshi are there?

Could you please clarify what you mean by "Yoshi" in this context? Are you referring to a specific cryptocurrency, a character from a game or media, or something else entirely? Without more information, it's difficult to give an accurate answer to the question "How many different Yoshi are there?" However, if you're referring to a cryptocurrency or token named Yoshi, I would suggest researching the specific project or protocol to determine the number of unique versions or iterations of that cryptocurrency or token that exist. It's important to note that the cryptocurrency and finance landscape is constantly evolving, so the number of different Yoshi or any other cryptocurrency could change over time.
