Tell me a material to reflect RF signals. I want to build a sphere of a material. Emit some RF signals. And these signals will bounce back from the sphere and I will read them...

I dont know why a sphere is in the picture for you. A corner reflector will reflect much, much more energy . Any metal will work: copper, aluminum foil, etc. Thickness is not important.
A corner reflector is basically what is used in light reflectors (like on a car). There are hundreds of sections of a cube molded into the plastic.
For RF, you may want the dimension of the cube to be on the order of 1/4 to 1 wavelength, if possible.

Nearly any metal will reflect RF signals. You need a smooth surface to reflect signals that can be easily read.

Everythings with high density would reflect RF signal.

They sell these switchboxes at RadioShack for about $40 $50, that will allow for av input and come out as RF. In addition it will also orgnize your wiring.

In general, any conductor will reflect radio waves. The radio waves impinging on the conductor surface induces currents that re-radiate the signal.
