Answer 1

You can create a custom module and use hook_form_alter.

You can then modify the form by adding drupal form elements.

function custom_module_form_alter(&$form, &$form_state, $form_id) {
  if ($form_id === 'user_register_form') {
    $form['account']['other'] = array(
      '#type' => 'select',
      '#title' => t('Other'),
      '#options' => array(
        0 => t('No'),
        1 => t('Yes'),
      ),
    );
    $form['account']['group'] = array(
      '#type' => 'text_format',
      '#title' => t('Group'),
      '#default_value' => '',
      '#format' => NULL,
    );
  }
}
