As far as I recall, it was never confirmed. Shinohara was the one who mentioned that Kaneki must've had several because I think he blew out one or two, but Kaneki kept regrowing his Kagune confirming that he must've had several. Judging by the fights with the Owl, it looks like the CCG makes a rough guess by trial and error. They fought Owl several times and made an educated guess that he/she had 6-8 Kakuhous.

The fight at Kanou's lab was the only time an investigator fought Kaneki and tried to keep track of his Kakuhous, but since it was only one fight, it remained undetermined. I reckon they know how many he has now, but I don't think it's been divulged to the audiance yet.
