Re: ferment temps
Wont kill yeast, but ferment will be slow if the volume is small enough to drop the temp towards ambient. Insulate the fermenter.

Re: ferment temps
Depends on the yeast. Many lager yeasts perform reasonably well down to 45F. Below that temp yeast metabolism seems to slow to a crawl and crap out. Many a whiskey gets fermented with ale yeasts that prefer warmer (50F - 72F) temps. Check the spec sheet on your yeast for it’s preferred temp range.

Re: ferment temps
As mentioned, some lagers will be able to ferment but very slowly (I don't think it's suitable for distillation) while a yeast Ale I believe falls asleep but you can wake him up by increasing the temperature ... if you don't have a heating source you put on the blanket around the fermenter.
