It is generally illegal to walk on the freeway as it is considered a restricted access road designed only for motor vehicles traveling at high speeds. Pedestrians are not allowed for safety reasons. If you need to walk along the freeway for an emergency, it's best to contact the authorities for assistance.
Yes. I personally can't quote any sources, but please do not stop and back up on a freeway. It is very dangerous and no doubt illegal.
about the same speed as freeway traffic
HELL no. What is wrong with you? Not only is it insanely illegal but it is extremely dangerous. Remember that you're not the only person on the road. Don't be a selfish person. If you don't get yourself killed you'll probably get someone else injured or killed and yes you'd definitely be at fault for BACKING UP on the freeway.
