You know, I'm writing an ancient Egyptian book, and I want to use ancient names of some countries, but I still haven't got them, so I turn to you for help. I need:
- Hatti
- Babilon
- Libia
- Siria
Thank you.

Have you tried googling it? If so, what did you find.... I don't know any off hand but will start searching for you.

You may want to get a copy of Breasted's Ancient records.
He has copies of translation which mention the "Asiatics"
I think Mitanni is named 'Naharina' (It's described as a region in Western Syria) (see http://nefertiti.iwebland.com/texts/amenhotep_iii.htm )

Other states and cities include: Djahi, Retenu, etc.

I think the libian people included for instance the Tehenu.

I don't know the names off the top of my head

well... apparently not a prosperous question... almost NO website info on that! I did find the following website which seems pretty comprehensive on ALL ancient civs.... give it a look..

Hatti - http://en.wikipedia.org/wiki/Hatti

Babylon - http://en.wikipedia.org/wiki/Babylon

Lybia - http://en.wikipedia.org/wiki/Lybia

Syria - http://en.wikipedia.org/wiki/Syria

Not sure if these are exactly what you want, Wikipedia is a great source for just about everything, in my opinion.
