Is it possible to receive wi-fi signals and display available networks on the screen.
work with Arduino.

Answer 1

Of the modules now, the cheapest seems to be ESP8266

Answer 2

Possibly, but quite expensive.
Here is an example module.

Answer 3

Maybe. Here is another version of the board: www.adafruit.com/product/1491 and the library for it: https://github.com/adafruit/Adafruit_CC3000_Library. You can also search on ebay.
I recommend to immediately look for both the library and reviews on the board.

Answer 4

It is much easier to take a router like mr3020 and connect a screen to it via UART / SPI.
