Different profile fields and refined user search

Hi

I have 4 questions regarding if it is possible with the lite if not then with the pro version:

1. Is it possible to get two different roles (e.g. company and person) that have different profile fields?

2. Can these different profiles have different groups in the profile e.g. for picture upload of recent work for the Person profile? The Company shouldn’t have that.

3. Can the different User (Company and Person) get a different theme?

4. Is it possible to search for the user profiles in buddypress in detail?
After I search for users and got the results I would like to have on the widget sidebar more options to refine the search.

E.g. when I’m searching for someone in a special city and get the results it would be great to refine it without doing a new search and putting in the same information again plus the new refining.

Besides that it would be great if the search could exist twice. One for one user group (e.g. cpmpany) and one for another user group (e.g. persons). Would this be possible too? Maybe if the search is integrated in different pages?

My versions:
Wordpress 3.5.1
Buddypress 1.6.4

Thanks a lot
