[name_f]Ariana[/name_f] is my favorite.
I like [name_f]Selena[/name_f] (though I really love the Spanish pronunciation, se-LAY-na)
[name_f]Milena[/name_f] is beautiful, but how are you pronouncing it?
I also like [name_f]Alexis[/name_f], [name_f]Alani[/name_f], and [name_f]Amayah[/name_f] (which will likely get misspelled a lot, due to the fact that there is also [name_f]Amaya[/name_f], [name_f]Amya[/name_f], Ammaya, and Amaia).
I’m not sure I really see [name_f]Layla[/name_f] as a nickname for [name_f]Aliyah[/name_f], it’s pretty, but a bit of a stretch!
