Why in my query is display two title?

Try this. The code has comments where modified.

<?php 

    // args
    $args = array(
                'showposts'     => 5,
                'post_type'     => 'post',
                'orderby'       => 'date',
                // 'order'          => 'ASC',
                'meta_query'    => array(
                    'relation'      => 'OR',
                    array(
                        'key'       => 'type_id',
                        'value'     => 'News',
                        'compare'   => 'LIKE'
                    ),

                )
            );


    // query
    $the_query = new WP_Query( $args );
            ?>
    <?php if( $the_query->have_posts() ): 
                $i = 0; 
                while ($the_query->have_posts() ) :
                    $the_query->the_post();

                    // First post
                    if ( $i == 0 ) : ?>
                        <div class="card mb-3">
                            <a href="https://wordpress.stackexchange.com/questions/337076/<?php the_permalink(); ?>" ><img src="<?php the_post_thumbnail_url() ?>" class="card-img-top"></a>
                            <div class="card-body">
                                <h2 class="card-title"><a href="https://wordpress.stackexchange.com/questions/337076/<?php the_permalink(); ?>" title="<?php the_title(); ?>"><?php the_title(); ?></a></h2>
                                <p class="card-text"><small class="text-muted"><?php the_time('F jS, Y'); ?></small></p>
                                <p class="card-text"><?php the_excerpt(); ?></p>
                            </div>
                        </div> <!-- Add this to close div with class card mb-3 -->
                    <?php endif; 


                    // Other posts
                    if ( $i != 0 ) : 
                    ?>
                        <div class="secoundposttak">
                        <?php //endif;  <-- Not needed, move it  below (before $i++ )   ?>
                            <a href="https://wordpress.stackexchange.com/questions/337076/<?php the_permalink(); ?>">
                                <img src="<?php the_field('thumbnail'); ?>" />
                                <?php the_title(); ?>
                            </a>
                        </div>

                    <?php endif;    // <-- Add this for  if ( $i != 0 ) :  ?>



                    <?php
                        $i++;
                endwhile;
           endif; ?>

            <?php wp_reset_query();  // Restore global post data stomped by the_post(). ?>
