No.
The direction of an object's motion is a component of its velocity but not of its speed.
An object's mass (m) can be changed into energy (e). Albert Einstein gave us the conversion factor - the square of the speed of light (c2). E = mc2
The speed of light in a vacuum, which is approximately 299,792 kilometers per second, is considered to be the fastest speed at which any object can travel in the universe according to the theory of relativity.
As the speed of an object approaches the speed of light, its kinetic energy approaches infinity. An object moving at the speed of light would require inifinite kinetic energy.
Since no object with mass can reach the speed of light -- such an object can only approach that speed -- the question is meaningless.
Electrons are able to travel close to speed of light.

No, matter does not turn into light when achieving the speed of light. As an object with mass accelerates towards the speed of light, its energy increases, but it does not transform into light. It would require an infinite amount of energy to accelerate an object with mass to the speed of light.
None. No astronaut or man-made object has ever gotten close to the speed of light. It is impossible for an object to actually travel at the speed of light.
To accelerate an object with mass to the speed of light, you would need an infinite amount of force, as the closer an object gets to the speed of light, the more energy it would need to accelerate further due to the laws of relativity. Additionally, as of our current understanding of physics, it is impossible for an object with mass to reach the speed of light.
Yes, photons do.
To calculate the speed of an object using a light gate, you would measure the time it takes for the object to pass through the gate. By dividing the distance between the light gate and the point where the object is launched by the time taken, you can determine the speed of the object at that point in time.
