As posted by sierpe:

Elis =

Victoriana =
فيكتوريانا
Ariele =

And the initials will be then:
إ.إ.ف.أ
So Sierpe already answered your question and wrote the intials for you, I just reproduced that for you.
Just one note: "e" means "and", so just don't take into consideration that letter next to it.
@Sierpe:
En portugais, "e" veut dire "et".
