Yes, your foot needs contact with the ground to walk, because it pushes itself off of the ground. With no friction, your foot could not stay on the ground to push off. It's similar to walking on ice except... impossible.
Walking would not be impossible, but it would be likened to trying to walk on ice. Friction opposes movement, which can also be translated into traction. The more friction, the more of an opposing force the object will feel. Since ice has no friction, slipping and sliding is a problem to deal with. But since the majority of ground material on Earth has some type of friction, the opposing force that it provides also allows the feet to remain firmly planted on the ground rather than slipping out from underneath.
If you ran you wouldn't be able to stop.
Without friction it would be impossible to stand, you would instantly fall down flat. Without friction it would be impossible to crawl. Without friction the only way it would be possible to move would be by using thruster jets, as they do on spaceships.
Without friction - climbing a rope would be impossible !
There are many examples. The simplest ones would be walking or driving a car. Without friction it would be impossible to walk or drive, as there would be no surface to push away from. Wheels of a car would just spin and the car would remain stationary. Think about driving on ice (ice still have friction, its just lower).
You would not be able to walk. Walking is the friction of your shoe againjst the ground. Without friction, you would not go anywhere. A good example, all though not completely frictionless, is ice. Walking on clean, clear ice is very hard because of the lack of friction.
Grip is a type of friction that people need in order to walk comfortably. Without grip, people would slide and have nasty falls.
Yes it would, thank God for rolling friction

For us, it would probably be bad. Without friction, it would be nearly impossible to get around. imagine walking around on ice all day, but worse.

it would be nearly impossible to stop cuz it is slippery
yes you wouldn't even be able to stand up because you would just fall over again Not sure why you have asked about "Rolling Friction"...there are other categories as well. But imagine you were wearing Magnetic Boots on a Ferrous surface. You could walk without "Rolling Friction".
One of the most important frictional forces to humans is the static frictional force that the ground exerts on a body. Without this force, walking would be impossible, cars would go nowhere.

Friction is fascinating because in so many situations we try to reduce friction, but friction is a necessary force, without which everything would be impossible. Without friction we would all be flat on the floor without any methods of directing our motion. We would randomly collide with things and then continuing moving in another direction. Without friction the slide at the playground would be really fast, but you could never climb the ladder to get on it. The swings would be useless since no one could get into them. So friction is necessary for playgrounds.

It is impossible to have no friction. If there was no friction we would be sliding all over the place, nothing would be balanced.
