>> Account type and infos

Maybe complex question I still dont find the way to finalize it :
A. ACTIVE TEMPLATE :
a.1 – kleo buddypress website
a.2 – wpmudev plugins
a.3 – woocommerce
a.4 – gravityform
a.5 – xfield buddypress

B – SITUATION
Everybody can create a profil its ok but everyone have the same question. I need different data for each kind.
I EXPLAIN :
I would like Visitor to create a profil and in this way be able to do different things
B1 : Level 1 member is a peaple
B2 : Level 2 is a pro and show a specific profil with specific data
B3 : Level 3 is a pro and can sell product

C – QUESTION
How can I have different field and members capabilities ?
C1 – If I select B1, its personal info and data (its like that today)
C2 – If visitor select B2, its personal and business info and data. At this time I can create another business field with xfield buddypress but I can’t Hide it for C1
C3 – if visitor select B3, its personal and business info and data. At this time I can create another business field with xfield buddypress but I can’t Hide it for C1. C3 offer a personal shop and a website. How can I allow this with fields, rôles and capabilities, How can I do ? (I dont find with pmp and switch to wpmudev membershippro2 but xfield and different field stay and its the second problem, I also ask to wpmudev)

Thank you Very Much
