Yes; Stars give off energy in the form of light, during the reaction taking place with their hydrogen and other elements.
This energy travels in the form of infra-red radiation, which travels in a wave (a ray), as radiation can travel in a vacuum, whereas the other methods of heat transfer cannot.
So while Stars do not "have" rays, they do give them off.
The sun emits sun rays it does not reflect them.
Bi-Convex lens can be used to focus the Sun's rays
If you are talking in terms of the suns heat being absorbed by the surfaces then I have the answer. Shiny surfaces naturally deflect the suns rays where as dark surfaces are easy conductors of heat as they naturally catch the suns rays. You will notice with leather or print on a shirt that it gets hot because the rays have nowhere to go. A shiny surface will just deflect it back.
Land
Yes, it does because the suns rays heat the the water so that is can evaporate
It does indeed reflect the suns rays.
About 17% of the suns rays get absorbed into our atmosphere
The thing which protects us from suns UV rays is the ozone. It is an allotrope of oxygen element.

Well when the suns rays hits our Earths atmosphere, the suns rays scatter across the world nearly and becomes blue skies...
The ozone layer is mostly affected the by the suns ultraviolet rays. This layer is present in the stratospheric region of atmosphere.
Sting-rays are a relative of the shark - the suns rays are strongest at the equator
