Unless you specify relative to what, this is a meaningless question.

It seems to be. There are a variety of theories on this. Some indicate that the expansion will eventually slow and reverse (the big crunch); others predict the expansion will continue to accelerate until even subatomic particles can no longer be held together (the big rip). Basically, nobody knows for certain what's going to happen. This is one of the big areas of cosmological research at the moment.
The speed with which a galaxy goes away from us can be obtained from the spectrum, through the Doppler effect.
The distance of the galaxy must be ascertained through other means, for example, one of the "standard candles" methods (certain types of stars that have a known brightness).
The expansion rate of the Universe, then, is obtained through a simple division. Or what do you mean with "mathematical proof"?
Compared to what? Any speed should be specified related to some other object. There is no such thing as an "absolute" or "real" speed.
The Solar System goes at a speed of about 220 km/sec around the center of the Milky Way.
Light, heat, and several other varieties of the same thing travel through space as
electromagnetic radiation.
Without getting into a whole semester of Physics here, I can assure you that there's
nothing mysterious or unfamiliar about it. It's exactly the same way that light travels
from the light bulb to the book you're reading, and the signal travels from the cell-tower
to the phone in your pocket, and the heat travels from the toaster coil to the bread.
Any speed should be specified compared to some object. The Milky Way's speed relative to the CMB (cosmic background radiation) rest frame is about 552 kilometers per second. You can convert that to miles per second or miles per hour if you like.
The question isn't clear; how fast does the Milky Way move in relationship to what? Any movement of an object must be specified in relation to some other object; there is no such thing as "absolute" or "real" velocity.
Here you can see the speed of the Milky Way according to different reference frames: http://en.wikipedia.org/wiki/Milky_Way#Velocity
Approximately 486,000 miles per hour on average. Depending on where they are in their orbit around the sun, their speed can be as low as 380,000 miles per hour or as high as 592,000 miles per hour.
It really depends what you will accept as an "object". The fastest known things are particles/waves that only travel at the speed of light, such as the photon / light wave, and the (still a little hypothetical) graviton / gravity waves. Next there are particles that travel very near the speed of light, such as the neutrino, and some extremely fast particles that come from outer space, as well as particles that go through a particle accelerator; in each of these cases, the difference in speed, compared to the speed of light, is insignificant. If you were thinking about larger objects, anything which falls into a black hole will be accelerated to very nearly the speed of light, too, by the immense gravitational attraction.
The Sun is moving.
How much the sun moves depends on what type of motion one is asking about.
There are several points to make however.
1. Five hundred years ago, there was a great debate about whether the sun went around the Earth or the Earth went around the sun. That was settled with the Sun being at the center of the solar system with the planets going around it. So, people said the Sun was the fixed center.
2. But, there is some movement to the Sun. Just as the Sun attract the Earth and other planets, the planets attract the Sun. The force of the planets on the sun do cause it to wobble some, but it is so small that it takes careful measurement to detect it. (As an aside, most of the planets that are discovered to be rotating around nearby stars are discovered because the stars wobble from exactly the same force of their planets pulling on them.)
3. The whole solar system is moving. The Sun is one of a hundred billion stars in our galaxy, the Milky Way, and they all rotate in a big swirl. It takes over a billion years for one complete motion around the galaxy, but we are actually moving very fast in this giant circle.
4. The whole galaxy is moving as part of the
Neptune's winds are the fastest in the solar system they go at a speed of 2000km/h. They are the fastest in our solar system and maybe even in the entire galaxy.

The solar system is believed to have formed about 5 billion years ago, and by the way, why do you call it YOUR solar system? Do you come from a different solar system? Because if not, then it's OUR solar system.
There are a few steps of a solar system project. You first have to study the solar system.
1) I am learning about the solar system in school. 2) I would love to see the solar system!. 3) Earth is a planet in the solar system. 4) The sun is the biggest star in the solar system.

The fastest moving planet in out solar system is Mercury, which is named after the roman god of speed.
Neptune's winds are the fastest in the solar system they go at a speed of 2000km/h. They are the fastest in our solar system and maybe even in the entire galaxy.
Going by the speed of light, it'll take 8.5 hours to reach Pluto from the Sun, about the length of the solar system.
In the furthest reaches of the Solar System is the Oort Cloud; a theorized cloud of icy objects that could orbit the Sun to a distance of 100,000 astronomical units, or 1.87 light-years away. Therefor at the speed of light it would take about 3.74 years to travel the diameter of the Solar System. However no object with mass can travel at the speed of light.
Yes, in theory, although currently our Solar System doesn't seem to have this tendency. If our Solar System gets near another star, it may in theory change its direction, gaining enough speed to be catapulted out of our galaxy.
The closer planets are to the Sun the faster their orbit speed
It takes approximately 230 million years for the solar system to orbit our galaxy at a speed of about 828,000kph (515,000 mph)
