How do I load taxonomy terms?
in Single Manner

    $term = \Drupal::entityTypeManager()-&gt;getStorage('taxonomy_term')-&gt;load(TID);
    $value = $term-&gt;FIELD_MACHINENAME-&gt;value;


Example : load title and language of term id =2 

    $term = \Drupal::entityTypeManager()-&gt;getStorage('taxonomy_term')-&gt;load(2);
    $title = $term-&gt;name-&gt;value;
    langcode = $term-&gt;langcode-&gt;value;


And for load Multiple as you wanted 

  $terms = $entityManager-&gt;getStorage('taxonomy_term')-&gt;loadMultiple($t‌​erms);
  foreach ($terms as $term) {
      var_dump($term-&gt;tid-&gt;value); //return tid of term
   var_dump($term-&gt;name-&gt;value); //return title of term
  }
