Is it possible, after completing one of the typeform, to send an individual code to the email of the person who just answered? So that, afterwards, they insert that same code in another typeform, and so there are not several answers from the same person?
+5Hi 
While there isn't an option to create an individual code, you could use our Hidden Fields feature to assign the codes for each respondent in the typeform URL. Then, you can recall this information and let the respondent know what is his/her individual code too. :)
Hope this helps!
