Probably not, but it depends on the depth of the pond. If the water truly all freezes, then they will not likely survive. In harsh winter areas they need a pond at least 1.5 meters deep. They are a hardy fish, but their immune system will shutdown around 10 C. The important thing is that the pond have enough depth to avoid freezing solid.
Yes cause only the top of the pond freezes koi will sink to the bottom when the top is frozen
It is very unlikely to survive but if the pond isn't deep then they will have a little chance of living
if your pond is frozen then put a crac in the pond and fish them out and put them in something large .
Hope the koi stay alive .

No they still need the oxygen we breath but they can't because the ice block's it out.
