Koi are generally slow swimmers unless they are being preyed upon or are ill. If your koi is swimming fast or erratically, check for signs of illness or injury.
Yes you can swim in it and they won't hurt you.
Very fast. I don't think their speed has ever been measured/calculated accurately though.
The Koi represents 'Good Fortune' for it to succeed to swim up stream.

Anything with a face should be looking inward and almost never outwards, and with Koi, they ALWAYS go upstream and never downstream.
