Ozone layer is situated in the stratosphere. It does not allow UV rays to enter.

Gamma rays from space are absorbed by the Earth's atmosphere. However, gamma rays can still be detected on the ground as it is naturally emitted by radioactive decay occurring in rocks.
Cosmic rays are continuously present in space - regardless of what day (or year) it is. Luckily, we are protected from cosmic rays on the surface of the Earth by the Earth's atmosphere and magnetic field. A small amount of comic rays can still reach the Earth's surface - particularly at higher altitudes.
UV rays are part of electromagnetic spectrum just like light. Some rays can be detected by the eye and some cant. The sunlight we see is the visible part of this spectrum that is why it is called visible light. Initially only light would reach the earth but now because of ozone depletion even UV rays reach the earth. So basically they are invisible because they are not part of visible light.
it takes about 8 min.
Gamma rays are a form of electromagnetic radiation, and thus they travel at the speed of light. If a star is one light year away, it will reach Earth in one year.
The amount of time it takes for ultraviolet rays to reach earth will vary depending various factors. Some common factors include time of day, latitude, weather conditions and so much more.

One part of the earth is facing directly at one side of the earth the rays from the sun and that is what makes summer and when the rays are pointing further from the sun is winter. because the rays are harder to reach the earth.
