The W, R, G from the thermostat appear in your photo to be correct according to the furnace’s diagram.
Compressor Red goes to Thermostat Yellow.
Compressor White goes to Furnace Yellow.
Thermostat yellow is the thin one bottom right.
It’s unclear which is “Furnace Yellow” as there are three. Two in your hand and a thicker one nearby. The diagram implies there is a terminal block with 5 terminals. But I don’t see one and the blue wire comes straight out of the transformer coils, so it's hard to identify which wires are the ones referred to by the diagram. I cannot tell what the other two yellows, and the green in your hand are for. They are not in the diagram. That green is not the thermostat G wire.
More photos might help. If you follow the Blue, White, and Brown wires that are (correctly) connected to the thermostat, do they go to a terminal block or to a place where they can be clearly identified and grouped with a particular yellow wire?
Here's another Question (that one about C wires) with a better photo of what I think is a similar furnace, and a more complete diagram. It looks like the correct yellow for the compressor white is the one in your hand. It's shown in the upper right part of the diagram that is missing from your photo.
However I still can't tell what the green wire in your hand is!
