I added the following code in your theme function:

function get_related_author_posts() {
    global $authordata, $post;
    $authors_posts = get_posts( array( 'author' => $authordata->ID, 'post__not_in' => array( $post->ID ), 'posts_per_page' => 5 ) );
    foreach ( $authors_posts as $authors_post ) {
        $output .= '<l i>< a>ID ) . '">' . apply_filters( 'the_title', $authors_post->post_title, $authors_post->ID ) . '</ a></l i>';
    }
    return $output;
}

On page user-profile.php, I put the following code:
<?php echo get_related_author_posts(); ?>

It shows 5 posts, but I want to show only the for profile author of this posts. Now it shows all the user profiles.Each author should have a list of posts in the profile. Tell me how to do it.

Here’s the code works for me:

<?php $curauth = (isset($_GET['author_name'])) ? get_user_by('slug', $author_name) : get_userdata(intval($author)); ?>
<!-- The Loop -->
    <?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
        <l i>
            <a hr ef="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link: <?php the_title(); ?>">
            <?php the_title(); ?></ a>,
            <?php the_time('d M Y'); ?> in <?php the_category('&');?>
        </l i>
    <?php endwhile; else: ?>
        < p><?php _e('No posts by this author.'); ?></ p>
    <?php endif; ?>
<!-- End Loop -->
