Is it possible to connect iPhone to Sound In port on PC running Windows 7? Is it possible through a male/male cable to route audio from my iPhone 6 to my computer through the Sound In port?
Yes, you can use the iPhone 6's headphone port to connect a male to male mini-stereo cable to a line-in/microphone port on a PC. Since you are going from digital to analog to analog to digital, you should expect the sound quality to be fairly poor.
