Some of your question is answered here:

1) By design, you cannot know whether aaa.onion and bbb.onion are
running on the same machine or are run by the same operator.

2) If either .onion site requires registration, you must be careful to
use different email userid and password on each, and those must also be
different from anything you use in non-Tor contexts.

3) If you check the tests at
    you will see how much browser fingerprinting is possible.  So you
must be careful not to change any settings that will make your browsing
session look different from any other person using TBB. 
TBB is designed to make all its users have the same browser fingerprint,
i.e. no unique id.
