In order to be able to paste from excel to multiple inputs, you will have to split the whole string in an array and then just change the value of every input. Let me show the code you need to add:

jQuery('.paste-me').on('paste', function(e){

    var data1 = e.originalEvent.clipboardData.items[0];
    if(data1.kind == 'string' && data1.type == 'text/plain'){
      e.stopPropagation();
      data1.getAsString(function(s){
        s = s.split('\t');
        if(s.length > 0){
        	jQuery('.paste-me').each(function(i,item){
        		jQuery(item).val(s[i]);
	        });
        
        }
      });
    }
  });
