Using custom views while looping through pages

Hello

Sorry for my English in advance ??

Im developing single view wp template.
In index.php I have loop that is giving me pages content, titles, thumbs etc.

I was usign this tutorial: https://www.themevan.com/build-an-one-page-portfolio-website-with-wordpress/

here is the loop:

<?php 

       query_posts('post_type=page');

        if (($locations = get_nav_menu_locations()) && $locations['primary_navi'] ) {
                $menu = wp_get_nav_menu_object( $locations['primary_navi'] );
                $menu_items = wp_get_nav_menu_items($menu->term_id);
                $pageID = array();
                foreach($menu_items as $item) {
                    if($item->object == 'page')
                        $pageID[] = $item->object_id;
                }
            query_posts( array( 'post_type' => 'page','post__in' => $pageID, 'posts_per_page' => count($pageID), 'orderby' => 'post__in' ) );
        }
                while(have_posts() ) : the_post();

                 ?>  

                    <div id="<?php echo $post->post_name;?>" class="page-contener">

                         <header class="entry-header">
                                        <h1 class="entry-title"><?php the_title(); ?></h1>
                                </header>

                               <div class='page-img'>
                                            <?php if (has_post_thumbnail()): ?>
                                                <img class="" src="<?php bloginfo('template_directory'); ?>/timthumb.php?src=<?php echo wp_get_attachment_url( get_post_thumbnail_id($post->ID) ); ?>&h=235&w=960&zc=1" alt="<?php the_title(); ?>"/>
                                           <?php else: ?>

                                           <?php endif; ?>
                                </div>    

				<div class="entry-content page-content">
                                    <?php the_content(); ?>
                                </div>

                    </div>

                <?php
                endwhile;
        ?>
        <?php wp_reset_query();?>

Now I would like to use custom view templates in that loop like contact page template, fullwidth, 1 column, portfolio etc.

How can I access something like page template type and use that template?
Ideal solution would be to detect page template in loop and then use that template, defined in standard “my-custom-template.php” with data provided by the loop.

I hope this clear enough :).
