Electrical Question for Receptacles in guest house
There is no requirement for GFCI receptacles anywhere. 

GFCI protection is what is required.  That can be in many locations - a breaker, switch, deadfront or indeed a receptacle.  Further, each can protect downline locations so they too are GFCI protected.  

Having more than one GFCI per breaker trip circuit indicates someone doesn't understand this concept and perhaps should not be designing wiring schemes.  Unless you have a very unusual situation, but that should only ever come up in retrofits, not new construction.  

There are restrictions on bathroom circuits which are beyond the scope of this question. Bathroom lights can be on a receptacle circuit that serves only that bathroom.  The lights do not need to be GFCI protected unless they are in the shower area. 

For the convenience of bathroom users, it can be helpful to have 2 or even 3 receptacle circuits (breakers) in a bathroom so someone can plug in both a hair dryer and a curler without tripping the breaker.  Each circuit needs a GFCI protective device.  That could be multiple GFCI receptacles; that is fine.
