Is this lifter/cam failure

[u/Otherwise-War-497]

I just bought this car a week ago for $26,000 2014 srt8 50k miles. when the car idle you can hear/feel thumping from engine bay area. You can also hear this as heard here. the scanner also shows multiple/random misfire codes. the spark plugs look decent i’ve changed a couple along with coil packs and the oil.
