Showing one post then the titles for the next 5

thats a mullet loop, you’re just substituting the title for the excerpt.

set your “# of posts per page” in the admin panel to 1
then put this code after the content tag:

<ul>
 <?php
 global $post;
 $myposts = get_posts('numberposts=5&offset=1');
 foreach($myposts as $post) :
 ?>
    <li><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></li>
 <?php endforeach; ?>
 </ul>
