Edit a "Create Account" form page

We have a working website in Joomla, and we need to edit the form on the page "Create Account". It's working, but we need to modify some fields. Everything that is modified there, also will need to be modified in 2 other pages: the page where the user see his account details, and the page where the user edit his account details. Here we have 3 links showing how are the pages today, and right after, a brief description of how they should be after your job: [login to view URL] [login to view URL] [login to view URL] Page1: We want the "Create Account" page to be like this: - Name - CPF - CPF is a unique ID number from Brazil, like Social Security Number. There's a system online for Joomla that recognizes if the CPF written by the user is fake or not. If it's fake, it shouldn't be accepted. I have no idea how to create this, but if you search online for CPF Brasil I'm pretty sure you'll find the solution. Also, this field should have a mask where user type numbers only, and the "dot" goes automatically into the right space. - User name - Password - Email - CEP - CEP in Brazil is the same as zip code. On the form, user should type his CEP only, and the next 3 fields will be autofilled by system (sytem will write down automatically street address, city and state). There's a system online for Joomla that recognizes this. If you search online for "CEP Brasil Joomla" I'm pretty sure you'll find the solution. - Street Address - City - State - Phone Number - this field should come with a mask like this (xx) xxxx-xxxx - Birth date - this field should come with a mask like this dd/mm/yyyy - Sex - this field should have radio buttons to choose male or female - Status - this field should have radio buttons to choose amateur or professional Beyong these fields, we'll also need to insert small explanation texts below some fields, example: "Below user name, write: User name can't be changed in the future." Page2: The page where the user see his account should have all the information from above. Page3: The page where user will be able to edit his account. All the previous fields should be editable here, except two: CPF and User name.
