With respect to 1 & 3 above (so microUSB power and Euler power), having the jumper in the DC_IN position will make it so the microUSB/euler DC_IN pin (as they are connected together) are providing power to the 5v OUT euler pin, and to the USB ports. Otherwise, if you have the jumper in the BAT position, the PMIC will provide regulated power. And if you don't have the jumper connected at all, you will have no power to the USB, or to the 5v output pins 
As I alluded to above, the microUSB input and Euler DC_IN are actually joined together, so if you provide power via the euler DC_IN pin, you can actually plug something microUSB into the pine64 and get power out there if you wanted to for some strange reason! Or if you needed to, the DC_IN pin is also a point to measure the supply voltage making it into the board.
