Hi Hammad, To install Debian 8 (Jessie), you only need either CD1 or DVD1. The extra CDs or DVDs are there to provide packages installable without Internet access. I personally prefer to install using the Live CD since I can test to see if everything works before I install.
Note that you also need to pick the CD/DVD with the needed architecture and desktop manager. Please do ask questions if you don't understand what I am taking about.
