Custom Fields, Media uploader, Attachments

There are a few different ways to get your values. One way is in the loop and another way is outside the loop. Here is a short code snippet that can be used to get them outside the loop

 ( untested )
 <?php 
   global $wp_query;
   $postid = $wp_query->post->ID;
   echo get_post_meta($postid, 'customField', true);
?>

You will want to change the ‘customField’ in the last line above to the name of your custom field

You might also read up in the codex

Here is another good source for you to look over

I would also try googling for some results on how to display them. There are tons of articles out there that will answer your question much faster than waiting for a response.
