For the second part, meta_query must be a nested array, like this

  'meta_query' => array(
    array(
      'key' => 'cs_industry',
      'value' => $relatedCat,
      'compare' => 'LIKE',
    )
  ),

for why it’s showing 5 instead of 3, this could be that your posts_per_page value is being overridden by a pre_get_posts filter, or something similar.
