  1. To get the comments use get_comments() and the current post’s ID.
  2. To get the URL fields only use wp_list_pluck().
  3. To remove the empty fields use array_filter() without a callback.

.

$comment_urls = array ();
$all_comments = get_comments( array ( 'post_id' => get_the_ID() ) );

if ( $all_comments )
{
    $comment_urls = array_filter( 
        wp_list_pluck( $all_comments, 'comment_author_url' ) 
    );
}

$comment_urls is now an array of URLS. Don’t forget to use esc_url() when you print those into your page.

You could also filter 'comments_clauses' to query for comments with a non-empty URL field only. That might be faster.

add_filter( 'comments_clauses', 'wpse_66056_get_urls_only' );
function wpse_66056_get_urls_only( $sql )
{
    remove_filter( current_filter(), __FUNCTION__ );
    $sql['where'] = $sql['where'] . " AND comment_author_url != ''";
    return $sql;
}
$all_comments = get_comments(
    array (
        'post_id' => get_the_ID(),
    )
);
$comment_urls = wp_list_pluck( $all_comments, 'comment_author_url' );
