I like Luna, very cute.
I love Fiona but really don't like Fifi, I would just go with Fi as a nickname.
Leona is kind of boring to me, again really don't like the Leelee thing, sounds too cutesy.
I like Maggie but not Magnolia, it's a bit too intense for my liking. I like Margaret nn Maggie, though.
Lacy is cute.
James is okay but strikes me more as a middle name for some reason. It's just kind of simple.
Love Arlo and Finn.
Don't care for Crosby as it immediately makes me think of Sidney Crosby so very much a last name in my mind.
I don't like Miles but Milo is sweet.
