I follow the steps but on my art page I only get the example 1 post to be displayed. I can't see example 2 and 3

<?php
/**

get_header(); ?>

    <div id="primary" class="content-area">
        <div id="content" class="site-content" role="main">

            <?php /* The loop */ ?>
            <?php while ( have_posts() ) : the_post(); ?>

                <article id="post-<?php the_ID(); ?>" <?php post_class(); ?>>
                    <header class="entry-header">
                        <?php if ( has_post_thumbnail() && ! post_password_required() ) : ?>
                        <div class="entry-thumbnail">
                            <?php the_post_thumbnail(); ?>
                        </div>
