Question about Electrical Supplies
I have 2 black wires, 2 white wires and a copper wire coming out of a core. I also have another copper wire coming from the wall. I am trying to hook it up to a gcfi/ddft/icta receptacle, please help....

If you can see which pair of black and white wires belong to eachother it will make things much easier. take a volt meter and test which black wire is the one coming from the breaker box. the white wire that is paired up with the black are the feeding wires to that outlet box those wires will go on the "LINE" side of the GFCI receptacle. The other black and white wires go to the "LOAD" side. (silver screw for white and brass screw for black) the two copper wires should be connected to the back of the outlet box and if so, take one of the wires and also connect it to the green ground screw on the GFCI plug. if they are not connected to the outlet box, be sure to connect them securely

You cannot replace the switch with a switch/receptacle combo because there is no neutral wire. The black and white that you see are both used as hot wires. One is the Line and the other is the Load.
You have to install another 2 wire cable or replace the existing with a 3-wire cable. A 3-wire cable has a black, red, and white, plus the bare ground wire

Take the black going to the light off the center and hook where the white going to the light is now....then hook the white to the light with the other white and you will be good to go...You almost had it right...
just a couple of adjustments....:-)

You're right, green goes to ground.
Black wire connects to Hot wire from breaker box
Red goes to Load (fan, light, motor)
Ok which wire on the switch goes to the Load?
And which goes to Hot from breaker box?
You can test or you can simply hook up the device. If it doesn't work, swap the two wires.
It just won't work until the 2 wires are correct.

You purchased a GFCI outlet.
You posted under GFCI combo switch and receptacle.
If you have different device, then add a comment.
On back of device are markings that show Line and Load.
These markings are associated with screws on device.
Black Hot wire connects to Brass-colored Line screw.
White Neutral wire connects to silver screw located opposite Line screw.
If you don't know which wires are Hot and Neutral, the testing steps are shown at bottom.
Your other two wires evidently go to a light, fan, or motor that is operated by the switch.
This is where the two wires that stick out of GFCI device are used.
Your Black Load wire connects to one wire, and your White Load wire connects to other wire.
Finally there are 2 screws left on GFCI device.
These screws are used if the Hot and Neutral wires go forward to another switch or receptacle box. This would require another Black and White wire in the box, and all devices from the GFCI forward would be protected by the GFCI.
As you know, the way electric circuits work is a Black Hot and White Neutral leave the circuit breaker box and travel to a junction box. From the junction box, the Black Hot and White Neutral travel to the next box, and then the next box, and so on until the last box is reached. Each box contains a switch or plug or combo device or a light fixture. In your case, the Black Hot and White Neutral may not send power forward to another box, and may just be a switch box that has a single wire to the light fixture, and that is the end of the circuit.
How to test for Hot and Neutral wires:
Separate your 4 insulated wires.
Turn power ON.
Test each wire to bare ground wire.
Tester will light up on Hot wire.
Now Hot is Identified.
Test Hot wire to each other wire in box, except bare ground.
Tester lights up on Neutral wire.
