No. Most comets are about the same age as the solar system as they formed with it.
The solar system houses the asteroid belt and the sun, and the outer solar system contains many comets and asteroids, some of them larger than Pluto.
The universe is older
yes we just don't know where it is
The Sun; planets; moons; dwarf planets; asteroids; meteoroids; interplanetary dust and gas; comets; solar wind...
Comets are often thought of as visitors from other solar systems. Solitary travelers in space. Asteroids can and do exist as "belts" and are usually found in groups that can orbit a central sun very much like planets. Composition can be very different for both objects. Both follow prescribed orbits, hence we are able to predict/know the returning date for Haley's Comet. Am not familiar with any data about asteroids with orbits as far reaching as comets. Because comets follow a predicted orbit, and visit our solar system at regular times, they could be considered part of our solar system the same way as band of asteroids. However, comets can and do leave our solar system and pass through others, so they are more visitor than permanent part of our solar system.

yes
The Solar System includes the Sun, planets, moons, asteroids, comets. Also some very tenuous interplanetary dust and gas.
No. There are more than that. There are currently 173 known moons orbiting planets in our solar system and many more orbiting dwarf planets, asteroids, and comets.
Everything in the solar system other than the sun itself is in orbit around the sun. This includes planets (such as the one we live on), asteroids, and comets.
The trajectories of all observed comets to date have been elliptical, indicating that they orbit the sun. A comet coming in from outside the solar system would follow a hyperbolic trajectory.
No. Comets are tiny compared to the Sun. They orbit the Sun, so they are in the influence of the Sun's gravity, because it is much bigger than them and everything else in the Solar System.
