When a box is already in motion, it has momentum which helps overcome inertia and makes it easier to continue moving. Starting from rest means having to overcome static friction as well as inertia, which requires more force initially.
Well, technically yes. Everything in the universe is moving at some rate. Not to mention that the earth is moving, thus everything on Earth is moving with it. !
If no net force acts on an object, the object will continue in its current state of motion. This means that if it is at rest, it will remain at rest, and if it is moving at a constant velocity, it will continue moving at that velocity.
Yes, it is possible for the train to appear to move while it is at rest if another train next to it starts moving, creating an illusion of motion. Additionally, if there are vibrations or movements in the surroundings that are transferred to the stationary train, it may also feel like it is moving.
An example of force being used to move a stationary object is when you push a door open.
It is more difficult to slide a crate starting from rest because static friction exists between the crate and the surface, requiring a greater force to overcome. Once the crate is already sliding, kinetic friction is less than static friction, making it easier to keep moving with a lower force.
Any force.

Newton's First Law doesn't state that an object remains at rest. That's only one option. If no net force acts on an object, it will either remain at rest, or - if it was already moving - continue moving at a constant velocity.Newton's First Law doesn't state that an object remains at rest.

Sharks die when they don't move, so even though they rest, they don't stop moving!
False. If it is at rest then it cannot spontaneously move and, conversely, if it is moving, it cannot come to rest all by itself. There must be some external force causing that change.

Objects start out as either a rest or moving. If they are at rest, they require a force to be applied for them to start moving. If they are moving, they require a force to either slow them down or to make them stop. That means that once something starts moving, it will move forever, unless a force slows it down. The catch is that the force can be friction.
Continue to move along its path. "An object in motion tends to stay in motion and an object at rest, tends to stay at rest."
Two or more forces that are balanced add up to zero. They have the same effect on masses as the complete absence of force, and they can't change the speed or direction of an object's motion.
