content block with more than 1 content items

The following code is a Drupal block made in php.

1) How can I implement more then one item? now i have test1 but i want test1, test2, test3 and test5.

2) how can i link a title for example test1 to my admin/settings/ menu? I want to link an item to node_import in Drupal.

  switch ($op) {
    case 'list':
        $blocks[0]['info'] = t('Stage administration block');
        return $blocks;
    case 'view':
        $blocks['subject'] = t('Stage administratie');
        $blocks['content'] = 'test';
        return $blocks;
  }
}

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;
      }
   }
}

You can either create multiple blocks as shown in Artusamak's answer, or you can simply add more content to $blocks['content'] if you want it in a single block.

$blocks['content'] = l('admin/settings/1', 'test 1') . ' ' . l('admin/settings/2', 'test 2');

Note, if you just want a list of fixed links, you can do that by creating a menu and adding links to it. Every menu is automatically exposed as a block. No custom code required.
