No, planets do not all travel at the same speed. The speed at which a planet moves in its orbit around the Sun depends on its distance from the Sun and its mass. Closer planets tend to move faster than those further away.
Velocity is a indication of speed and direction, so the fact they travel around it means that the direction is continually changing and, therefore velocity is continually changing. Kepler was the astronomer who discovered the laws of motion for the planets. Newton, a century later, derived the laws from his laws of gravity and motion. The first law of planetary motion states that planets orbit the sun in an elipse. So the speed is continually changing.
False. While most comets orbit the Sun in the same direction as the planets (counterclockwise when viewed from above Earth's North Pole), there are exceptions. Some comets have retrograde orbits, meaning they orbit in the opposite direction of the planets.
No. The farther away you get from the sun, the slower the planets orbit. (and the sun looks smaller!). By the way, even if the planets were all moving at the same speed, they still wouldn't be lined up, because the distances traveled by planets with each revolution around the sun would be different. Therefore this question is reasonable. (this is another person) they do orbit more slowly, Newton's law of universal gravitation states that the larger the mass of the two objects and the closer together the objects are, the greater the force of gravity between the two objects.
There isn't one. They all orbit in roughly the same plane. Pluto orbits in a different plane, but that's not classed as a planet now, of course.

no they do not
No, planets do not share the same orbit. Each planet in our solar system travels along its own distinct path around the Sun. The varying distances and speeds of planets in their orbits prevent them from sharing the same orbit.
Because their distances are not the same from the Sun. Minus this factor, it is impossible for any planets to orbit on the same orbitation.

all the planets have the same orbit just different orbit rings
Pluto has the longest orbit in length as it is further away from the sun than the other planets. If we model the orbit of all the planets as perfect circles, we can see that planets further from the sun give orbits which are larger circles, and larger circle have larger circumferences, which are the longer orbits. Even if the planets orbited at the same speed, Pluto would take longer to orbit as it has further to travel. Pluto doesn't orbit at the same speed as other planets - it orbits more slowly. This means it takes even longer to orbit the sun. It orbits more slowly as it is further out and the sun exerts less of a gravitational force on Pluto than on the other planets, and it is this gravitational force which causes objects to orbit around the sun. In fact, the sun exerts 1600 times as much force on Earth than on Pluto.

Yes asteroids orbit the sun counter-clockwise, just like all the planets
