If each wifi router is only allowing the connection (through MAC address filtering) of the 7 RPi's in it's row, and each is on a different wifi channel, then I figure that the rf floating around in the room shouldn't cause too many confliction problems.
Remember there are only 3 completely separate wi-fi channels on the 2.4GHz band: 1, 6 and 11. All the other in-between numbers overlap these to some degree. (Not sure what the story is on 5GHz.) At the University, I noticed that all the wi-fi access points were set on one of these three channels, even though there were far more than three of them that I could spot at the location I was at. It seemed to me to make more sense to spread them out, so you got less than 100% interference from (nearly) any other access point.
