Sort of but really its 6 as you add a sub bass or sub woofer, to take the low frequency from your main speakers. So usually you would have Two front speakers, Two Rear Speakers and a Centre speaker for 5:1, but 6:1 you have a seperate speaker to deal with low bass levels and 7:1 is two seperate speakers for low bass. You would be surprised how much difference in sound quality is lost from not having a speaker that can deal with the low frequencies.
