That depends

That depends on if he wants each screen to be independent of the others. If he does, then no. If he doesn't mind two monitors mirroring two other displays, so you have a 2x2 setup of two sets of dual monitors, that could be done with relative ease.

He could try using some sort of USB based video card, which might be tolerable for a largely static display. Maybe some kind of status update program running on it, like say activity monitor. For the most part he would just look up at it as needed, there would be little to no actual using the display. Much beyond that, and USB based video cards are simply not going to cut it.

The iMac only has connections enough for two monitors, and there's just no way to change that. A Mac Pro would allow for a second or even third video card to be added in, each one capable of driving at least two display. With an iMac though, the best you'll get is two independent displays, and then a device that will let you mirror those two displays onto another set of displays. Of course any mirrored display panel would need the same resolution as the iMac, so if it's a 27" model with a higher than 1080p resolution, that could get expensive.

So, I'd just say the short answer here is: No.

And they have added 2 or more at a time.

But speed is limited to USB speed so for some things it's fine but for gamers they'll have to get the Mac Pro.
