Can you suggest some good book for newbies which gives a solid historical background and good understanding in projective geometry ?
(I have zero background in projective geometry, and the only geometry I know is some rudimentary Eucledian Geometry. I was learning projective goemetry from EGMO Chapter 9, but I couldn't properly understand "projective plane", "points at infinity" etc)
A good reference is Coxeter's book Projective Geometry. The first chapter should provide enough orientation to get you started, should you choose then to go elsewhere. But you might as well stick with the entire book, if you want to learn the subject.
Other good discussions of the history are in Jeremy Gray's Worlds Out of Nothing and the last chapter of Cornelius Lanczos's Space Through the Ages.
