Question

What would be the best way to write this block of PHP instead of listing each number??

  <?php     $name1      = get_post_meta(get_the_ID(), 'ch_client_name1', TRUE);
            $name2      = get_post_meta(get_the_ID(), 'ch_client_name2', TRUE);
            $name3      = get_post_meta(get_the_ID(), 'ch_client_name3', TRUE);
            $name4      = get_post_meta(get_the_ID(), 'ch_client_name4', TRUE);
            $name5      = get_post_meta(get_the_ID(), 'ch_client_name5', TRUE);

            ?>

And here is the HTML that I will be using.
So I will want the list to display each of the 5 names.

            <li id="<?php the_ID(); ?>" ">
                  <?php echo $name1; ?> 
            </li>

You can do like it:

<?php

  for($i = 1; $i <= 5; $i++) {
    $nameN = "name{$i}";
    $$nameN = get_post_meta(get_the_ID(), "ch_client_name{$i}", TRUE);
    // or $name[$i], if you can

    ?>
      <li id="<?php the_ID(); ?>">
        <?php echo $$nameN; ?> 
      </li>
    <?php
  }
