                if(jQuery(this).val() == 'template-1.php') {                    
                jQuery('#gallery-metabox').show();
            } else {         
                jQuery('#gallery-metabox').hide(); 
            }

Here is the code, add your template file names in TempArray,

jQuery(document).ready(function() {
    var TempArray = [ "template-1.php","template-2.php", "template-3.php","template-4.php" ];
    jQuery('#gallery-metabox').hide();
    jQuery('#page_template').on('change', function(){
      if (jQuery.inArray($(this).val(), TempArray) !== -1) {
        jQuery('#gallery-metabox').show();
       } else jQuery('#gallery-metabox').hide();
     });                 
 });
