you can't
yes
You are only allowed one account, as per Facebook rules. If Facebook suspect that two accounts from the same IP's are the same person, they will disable both accounts.
No
I have done it you just put in the same email address and then do whatever you want after that
No two people can have the same gmail address. If there are 2 accounts, there will be 2 different email ID's. The Facebook account will be different in that case too.
Yes you can, you must wait 2 weeks until your account is PERMANENTLY DELETED, then you can make another one using the same e-mail.
Yes it is possible but it cannot be under the same email address you would have top make a new email account in order to do this

You can't, sorry.
Nope :P
No, it will require a different email address than your 1st one.
as long as you a different email address and password for each of the accounts it will allow you to create as many accounts as you want, just sign out of one, and at the log in screen, select create account
