How to list posts in a Blog page on a particular criteria

• To Fetch and display all the posts in a page.
  (From the current scenario, it displays title and tag name.)

<?php
$args = array(
'post_type'=> 'post',
'orderby'    => 'ID',
'post_status' => 'publish',
'order'    => 'DESC',
'posts_per_page' => -1 // this will retrive all the post that is published 
);
$result = new WP_Query( $args );
if ( $result-> have_posts() ) : ?>
<?php while ( $result->have_posts() ) : $result->the_post(); ?>
<?php the_title(); ?> 
<?php the_tags(); ?> 
<?php echo "<br>"; ?>  
<?php endwhile; ?>
<?php endif; wp_reset_postdata(); ?>

• Filter according to tag slug

'tag_slug__in'    => array('popular'),

• To list only three items

'posts_per_page' => 3
