Doubts about how the product works and compatibilities

Dear,
 
My name is Marcelo.
 
I’m Brazilian.
 
I live in Brazil.
 
I’m not fluent in English.
 
I loved the “DW Question & Answer” plugin and I want to ask some questions:
 
1. The “DW Question & Answer” plugin is compatible with WordPress 3.8.1, BuddyPress 1.9.2 and bbPress 2.5.3? (since these are versions with which I will work) ?
 
2. The developer of the website will have full access to the source code and he will can make customizations / changes in “DW Question & Answer” plugin?
 
3. Can the website developer translate all Front End (user interface) of “DW Question & Answer” plugin for Brazilian Portuguese language?
 
4. Can I add or remove categories?
 
5 In demo video users have a profile and have a photo in your profile. In the plugin where the users upload your photo? Where they make the registration of a profile? This is done through the BuddyPress?
 
6.The “Search” has the “auto-suggest feature” ?
 
7. “Auto-suggest feature” of the “Search” is compatible with the Brazilian Portuguese language?
 
8. The “title field of question” has the “auto-suggest feature”?
 
9. “Auto-suggest feature” of the “title field of question” is compatible with the Brazilian Portuguese language?
 
Thank you.
 
Marcelo.
