I took about 5 puffs two months ago and it was my first time smoking in about six months what are my chances of passing this hair follicle drug test?

Not perfect but fair, when is the test? Who is it for?

For the most part I think you will be negative. If they are taking hair from the head you should be negative. If they take body hair it all depends on how much weed you smoked 6 months ago. My advise would be not to get a hair cut until you get the results of the test. A hair drug test is meant to show consistent use over time. A 1.5 inch sample, cut at the scalp line, will go back 90 days.
