Send Email Based on User's Answer

1. Can you program your form - where if the users(person filling out the form) selects a specific radio button - it will email additional email addresses I put in?

4. When a user submits a form can I have it go to an email address, as well, as the info go to your site?   

If I understood your first question correctly you want to send an email based on the response inside of the form. You can achieve that with conditional logic.
