It's okay. I prefer
Clara.
I dislike
Fernanda.
I think people will mispronounce it. It sounds like kee-AH-ra in Italian but usually become KYAH-ra when said quickly. I think people will say chee-AH-ra or see-AIR-a or chee-AIR-a or something like that.
Chloe Fernanda flows well but I dislike
Fernanda.
Chiara goes with
Luisa, the others are okay with it but don't work that well. In my opinion
Chiara goes with names like
Alessia,
Giulia,
Arianna and
Sofia.
