        $('.forSlowMo:hidden:first').fadeIn();

Answer 1

$(function() {
    // Start showing the divs
     //showDiv();
     showDiv2();
});

function showDiv2() {
// If there are hidden divs left
if($('.forSlowMo:hidden').length) {
    // Fade the first of them in
    $('.forSlowMo:hidden:first').fadeIn();
    if($('.forSlowMo:hidden').length > 1)
        $( ".forSlowMo" ).fadeOut( 1500, function() {});
    // And wait one second before fading in the next one
    setTimeout(showDiv2, 100);
}

}

这可以是您的答案吗？

customfadeOut($('.forSlowMo').first())
  
function customfadeOut(element) {
  if (element.length) {
    element.fadeOut({
      duration: 1500,
      easing: 'linear',
      done: function() {
        customfadeOut(element.next('.forSlowMo'));
      }
    });
  }
}

.forSlowMo {
  margin-bottom: 25px;
  padding: 25px 5px;
  border: 1px solid #000;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div class="forSlowMo">first content</div>
<div class="forSlowMo">second content</div>
<div class="forSlowMo">third content</div>
<div class="forSlowMo">fourth content</div>
