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

Answer 1

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;
}
}
}

Answer 2

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.
