It's Gaelic, meaning "fair, pale". Usually spelled Fiona
Yes! it is.
There isn't any proof that Fionna has a last name yet. Judging the fact that she is the gender-swapped version of Finn, she might inherit farm-world Finn's last name, which is Mertens. However, both Finn and Fionna are considered Finn/Fionna the Human, so there title could probably also serve as a type of last name maybe.
It's not typically a boy's name, but there is the name 'Fionn' which is an Irish name.
