We don’t have any restrictions, other than: You need to sell your content under a name under which you can lawfully do business and (if the content is paid) accept payment. So, anybody can do business under their personal name, and you can use a company name if you have a legal right to do that in the USA and the country where you reside.
See ://en.wikipedia.org/wiki/Doing_business_as for guidance on whether you need to go through an official company registration process in order to “do business as” under a name besides your personal name. And, of course, you cannot use a name which infringes someone else’s registered or common-law trademark.
