Creating mixture of shortcodes to use in the visual/text editor

I suggest to just append the other things to the content without editing the templates

add_filter('the_content','hang_my_specific_things_on_the_content');

function hang_my_specific_things_on_the_content($content)
{
  // shortcode0 is appended before content
  $content = do_shortcode('[shortcode0]').$content;

  // these are appended after the content
  $content .= do_shortcode('[shortcode1]');
  $content .= '<img src="https://wordpress.stackexchange.com/questions/312880/someimage.png" />';
  $content .= do_shortcode('[shortcode2]');

  return $content;
}
