There is no reason you can’t set some rules, run validation, then set some more rules and then run validation again.

$this->load->library('form_validation');
$this->form_validation->set_rules('username', 'Username', 'required');
if ($this->form_validation->run() == FALSE) {
    // Do whatever you do on fail
} else {
    $this->form_validation->set_rules('email', 'Email', 'required');
    if ($this->form_validation->run() == FALSE) {
        // do whatever you do on the 2nd fail
    }
    // do whatever you do on success
}
