You can add range at the end of the query like [1-10] and if you want the first record then just put [0] at the end of the query. If you want specific record then put its number at the end of the query like [5] or [3] etc.
duedate=maintanance_table.objects.values_list('maintanance_todate').filter(user_email=abc).order_by('maintanance_todate').reverse()[1-10]
checkstatus=maintanance_table.objects.filter(user_email=abc).filter(maintanance_status="PAID").order_by('maintanance_todate').reverse()[1-10]
