There's 5 of them.

Which can be used for wifi? Which should be used for wifi 2x2 channels, 1x1 channel, and 3x3 channels? Which can be used for bluetooth (if any?) Which can be used for WWAN and for WWAN what frequency ranges are supported (IE is 700mhz LTE ok)?

 

Three should be routed to the half-height mPCIE slot, those are for Wi-Fi, two should be routed to the full height mPCIE slot, those are for WWAN. Use the black and white for a 2x2 Wi-Fi card. If you aren't certain, post a photo of the innards of the laptop and I'll identify them for you.
