To parse Json Array

Hi friends....

Presently I am working on a project in which I want to control my home ap0pliances from anywhere in the world. For this I used ESP8266 to send HTTP request to a URL and receive a response. The response is generated is in Json (after I seperate it from the rest of the HTML body). further this Json is given to arduino UNO over a Serial communication.

Now, after receiving this at arduino I am stuck here as I dont have any idea how do I parse the received Json or how do I store it to use it further. Here is the Link from where my ESP fetches it

I have gone through ArduinoJson and aJson library but it put me in confussion even more.
Please help me with your suggestions.](
