apparently, there are some people who are comfortable using these ordinalities for these phrases up to the 7th:

"first off" - 18,800,000 results

"first off" + "second off" - 889,000 results

"first off" + "second off" + "third off" - 64,100 results

"first off" + "second off" + "third off" + "fourth off" - 10,900 results

"first off" + "second off" + "third off" + "fourth off" + "fifth off" - 3,530 results

"first off" + "second off" + "third off" + "fourth off" + "fifth off" + "sixth off" - 2,050 results

"first off" + "second off" + "third off" + "fourth off" + "fifth off" + "sixth off" + "seventh off" - 463 results

so my educated guess is that if you were a decriptivedescriptive (vs. a prescriptive) grammarian, you would think that based on these searches that there are groups of people not only comfortable in using "first off" with "second off" but are also comfortable using the ordinalities :)
