Yes
A down stream receptacle that is connected to the upstream GFCI will be protected. If the downstream receptacle senses a fault the upstream GFCI will trip.
Yes, there is no reason why this can not be done. In fact a benefit of this is that every receptacle downstream from this new receptacle will also be protected by the GFCI receptacle.
GFCI's are not used to protect a switch they are used to protect an outlet where something is plugged in.
Your question sounds simple but it isn't. There are two ways of wiring a light to a switch. One is to bring the hot and neutral wire to the switch box and from there run wires from the switch to the light. If this is the case you can install a GFCI on the circuit. The other way is to bring the hot and neutral wire to the light and from there run two wires to the switch and switch the light that way. In this case you cannot install a GFCI to in the switch box. <<>> The way you want the circuit to work has to be laid out as follows. Method one, the circuit that now controls the bathroom devices can be changed to a GFCI breaker. This is probably the quickest and cheapest, unless the job is new construction. Method two, if new construction use this method, as tearing walls open to get to the wiring will become costly. Where a supply circuit comes from the service distribution panel the first device on that circuit has to be a GFCI receptacle. This device has secondary terminals on it, that if connected every device downstream from it will also be protected. So if you supply the two way light switch that controls the vent fan and a bathroom light from the secondary terminals from the GFCI receptacle they will be protected.
Not if the GFCI breaker is supplying the circuit you are wanting to put the GFCI receptacle into.
A down stream receptacle that is connected to the upstream GFCI will be protected. If the downstream receptacle senses a fault the upstream GFCI will trip.
The terminology down stream refers to an electrical circuit and where devices are connected into the circuit. In reference to the breaker that feeds the circuit everything is down stream from it. If a GFCI receptacle is added into the circuit as the first device, the GFCI can be wired to allow all of the regular receptacles to be protected down stream from that GFCI. Every device added to the circuit will be down stream from the one that is ahead of it. The only device that will not have something down stream from it will be the last device in the circuit.
Most probably the receptacles downstream from the GFCI would not be protected by the GFCI receptacle.
If the test switch is faulty then there is no convenient way to determine if the GFCI is functioning, and technically, if the test switch is faulty, then as it is a part of the GFCI, the GFCI is faulty and should be replaced.
GFCI Breakers are quite a bit more expensive than a GFCI outlet. More often than not a typical residence will need only a handful of GFCI outlets that combined together will be cheaper than a GFCI breaker. If you need to protect a series of outlets with GFCI protection you can simply connect the rest of the outlets on that same circuit downstream from the first outlet on the line and make that the GFCI. All you have to do is connect all the other outlets to the LOAD side of the GFCI outlet. If a GFCI fault occurs in any of the outlets down stream they will trip that very first GFCI plug you placed and keep you safe.
GFCI receptacle has the ability to protect all receptacles down stream from the device. One way to see what is on the circuit after the GFCI is to trip (test) the device. Every thing that is connected downstream will shut off and there will be no voltage present to test. Any outlets ahead or upstream of the device on the same circuit will not be effected. <<>> Trip the gici. If the outlet goes out it's after, if not, it's before.

Shut the GFCI off at the panel breaker. You can remove the down stream load right at the GFCI. Then reapply the power and keeping your fingers clear of the wire terminals, trip the GFCI and reset it. If it stays reset the trouble is down stream from the GFCI. To trouble shoot down stream remove all plugged in devices and try a reset. If still no reset remove the hot wire in the hard wired fixture and try for a reset. If still no reset buy a new GFCI.
there should be 5 wires, hot and switched hot for the switch and hot, neutral and ground for the gfci receptacle.
Find the Hot side of the switch (Where there is voltage regardless of position of toggle on switch). Tie in new Black wire to GFCI. On wire nut with white wire tie in new white wire to GFCI. Do the same for the bare ground wire, if there is one.
