Facebook Terms.

Item 4. Registration and Account Security

Paragraph 2.

You will not create more than one personal account.

[pri✍]

If you must make another FB account, do not use the same email address or phone number. Those account will kriss-kross and difficult to untangled, just read someone having this problem (log in A, opened the B); that is aside than the possibility of shutting down all your FB account by FB if they caught you.

I don't think that you can put another Facebook account to same yahoo email. You need to make another yahoo email id for another facebook account.
Otherwise you can unattached your yahoo id with your old facebook account and then you can attach your new facebook id with your old yahoo email id.
