Where can I find how to use those rf transmitter/receiver
From the ali pages, the chip seems to be an LT8900 (Some ali vendors claim it has a NRF24L01, which I think is wrong. Check the marking on your modules.).
As you asked for info on how to use a SPI interface, I guess implementing a driver for this chip is way over your head. But this guy seems to have made and arduino driver for it, so you could try that.
Note that this is a 3.3V chip, so when you use a 5V arduino you will have to level-shift.
@nanofarad: I didn't check this chip, but radio chips often have both a CE pin that puts the chip in low-power mode, and a CS pin for the SPI interface. I think I recall a chip that, for greater confusion, swapped those pin names.
