GFCI = Ground Fault Current is what they are now called, there maybe a slight difference.
A GFCI receptacle is most often the first receptacle on a circuit then all the other receptacle down the line are also GFCI protected, if properly wired.
Actually GFCI means ground fault circuit interrupter. They do not trip on over current. They trip if there is a ground fault (basically an abnormal leak of current to ground) in that circuit, as little as 5 ma.
There are however combination breaker and GFCI that goes inside ones breaker panel..

Those breakers are insanely pricey at $75 each and you can tell it is not a standard breaker as it has a White Neutral pigtail wire that must be connected to the Neutral Buss bar..
As far as I am aware, GFCI breakers are not available in Duplex or Twin format..
As far as separate GFCIs wiring goes, not all outlets on that circuit may be wired through a GFCI. GFCI can be inserted anywhere in the circuit depending on what outlets need to be protected..
So, you can find some outlets that may be upstream (before the GFCI) and not GFCI protected if they are not in a wet location and any outlets downstream (after GFCI)of the GFCI will be GFCI protected as long as they were connected to the load side of the GFCI..
