If you refer to the documentation of hook_block, you can declare several block inside one hook.

The $delta argument is here to help you differenciate which block your are rendering.

About your links in the title, just use the l() function when you are setting the $block['subject'] value.

Example:

function planning_block($op='list', $delta=0, $edit=array()) {
  switch ($op) {
    case 'list':
      $blocks[0]['info'] = t('Stage administration block 1');
      $blocks[1]['info'] = t('Stage administration block 2');
      return $blocks;
    case 'view':
      switch ($delta) {
        case 0:
          $blocks['subject'] = t('Stage administratie');
          $items = array(
            l('Item 1', 'admin/settings/1'),
            l('Item 2', 'admin/settings/2'),
          );
          $blocks['content'] = theme_item_list($items);
          return $blocks;
        case 1:
          $blocks['subject'] = l('admin/settings/2', t('Stage administratie 2'));
          $blocks['content'] = 'test 2';
          return $blocks;
      }
   }
}
