Could be on any breaker; no official rule for where to put a doorbell.

Probably several ways to skin this cat. One would be to put a voltmeter
on the transformer (that's the thing that supplies low voltage
power--typically 16-24 volts--to the actual doorbell) and flip breakers
until it goes to zero volts (assuming the transformer works). Probably
the safest way; that secondary (low-voltage) side of the transformer
isn't going to hurt you if you get shocked by it.

Friend told me that if I just touch one wire at a time, I won't get
shocked.
T/F? Makes sense ; circuit not completed; but hard to isolate wires
in small space.
How cope?
