If the name is not IN Spanish, then it has no meaning in Spanish. If you want to know how to say that name in Spanish, you would say it the same as you say it in English, since it has no translation in Spanish. Many names have no translation in languages other than the one they are in originally.
Fiona is just a name, it doesen't exist in Spanish, sorry.
Since Cheez-Its are a brand name, you just say Cheez-its in Spanish.
