are there any species on earth that would survive in an ammonia, chlorine or SO2 atmosphere that could be a “template” for biology on other planets?

So no then?

We have found life already in many inhospitable places on Earth, where it would be normally thought to be impossible.....deep sea vents, hot springs, etc. Also the early atmosphere of Earth would have probably contained much less O2 and plenty of CO2, Ammonia, and such, due to the number of Volcanoes etc.
