Users with Multiple Role : Does this work ?

Hi there
Im wondering if WP File can do the following before I purchase it.

1. All my files will not be available to public - you neeed to be a subscriber (member / registered)
2. All registered users can see only categories which are allocated to them - based on their RANK (therefore users will be allocated 2 or more roles)

Example: User 1 with RANK 1 , can see only files that are RANK 1 and you need to be a subscriber
User 2 : Can see all RANK 1 files, RANK 2 files and Subscriber files - but cannot see any files that are RANK 3, RANK 4 etc.
User 3 : Can see all RANK 1, RANK 2, RANK 3 , general Subscriber file, but not RANK 5

Hence , one user, may have multiple ROLES allocated to them, and the categories wil be allocated only for RANK 1 or RANK 1 & RANK 2 etc.

Another way to imagine this , is:

: A student must register on their schools website. A Year 7 student can only see Year 7 content - but a Year 10 student can see all Year 7, 8, 9, 10 content....

Please advise.
Thanks in advance
