Freelancer's lore is pretty damn lazy in almost all respects with no clues on who escaped on what sleeper ship other than a general guess. You could easily include the Americas aboard the Liberty, Commonwealth nations on the Bretonia, Nordics on the Rheinland and anyone from the Asia region on the Kusari. You could even guess the Gallia could include Polynesians and Belgians.
The Maltese do speak their own version of Arabic but many are still fluent in both Italian and English so you've got a wide playing field there.
