I agree with Jerry. You might hear an English speaker say numbers 6 and 8, although the subject 'One' seems to be the wrong register - we'd be more likely to say the more informal 'You could fry...'. I would also add number 1. In the UK, at least, it's not uncommon to say 'It's scorching' on an extremely hot day.
As for the other sentences, most sound like translations from another language, written by a non-native English speaker. They range from the possible but unlikely (such as 7), through the grammatically dubious (2,3) to the downright nonsensical (12).
