The fiery plume is the Afteburner which is in the aft most portion of the engine. the case and exhaust nozzel are designed withstand that kind of heat. The engine does not directly touch the exterior of the fusealge so the heat transfer is not as great as you would think.

The unique metal composites around the engine exhaust prevent the exterior of the plane from melting at the extreme temperatures the Falcon reaches.

First, high heat metals are used like titanium, nickel based alloys, and stainless steel.
Second, mostly for the internal components of the engine, the metals are cooled using bleed air from the engine compressor and bypass air from the turbofan. While this air isn't exactly cool, it's much cooler than the combustion gasses exiting the engine.
Only about 10% of the air going through a jet engine is used for combustion, the rest is used for cooling and as a thrust medium.

The part near the exhaust is heat resistant.

Metal does not burn unless pure oxygen is induced to the mix. and even then it is 1500+ temp and contrary to popular belife jet fuel is a pure grade of kerosene ,not that hot !

After burner duct is heat resistant metal and air cooled.

simple- there's a cooling system, either antifreeze or cooled water flows around the pipes, only on the outside, in the jets themselves, does the gas ignite.
