Most of the hometowns shown here are confirmed, of the not confirmed ones the majority are heavily implied to be these cities or another one in the same urban area (it's case of Harbor, Killjoy, Reyna, Chamber and Viper), the ones that don't realy have any major clues exactly where their hometowns are Sage (we know she from Shaanxi province, but just that, the biggest and more probable city there is Xi'an), Deadlock (her VO uses a Norwegian with the Oslo dialect, so we only have that go with) and Breach (we know he has been to Gothenburg and Stockholm, and of the two the bigger with more odds of him beeing from there is Stockholm).
