Answer 1

You can loop throgh query records whit an implicit cursor (which automatically manages the open cursor, fetch and next record):
  for rec in (select intime,outtime,barcode,attend_date from dail_att; )
  loop
       t_in :=rec.intime;
       t_out :=rec.outtime;
       t_code :=rec.barcode;
       t_date := attend_date;
         PUT YOUR CODE HERE ... (if ..then... elsif... logic)
         you can avoid setting variables 'cause you can directly use the implicit cursor variables: rec.intime etc.
  end loop;
END;Anyway, I suggest you to check the where condition of your block ... because if not all data are retrieved there should be a problem in your query ... so even the cursor (if based on very same query) will return less data than expected.
