Are there? I just searched on Ad Hoc Partyand I couldn't find anyone. ):
Yes, there are. Check the lobby D1. If there aren't any players, you're just on at a bad time, check later.
Also, please refrain from making multiple threads/posts on the same subject. It is not going to get your question answered any faster.

European ad-hoc is pretty much deserted from dissidia players. The few europeans who still plays has moved to US ad-hoc.
