1.

->  J32 (Pin 1)  - VCC_SYS       ---  5V, 1A
->  J32 (Pin 2) - CIF_PWR_EN  --- （GPIO1_C6） 3V
->  J32 (Pin 3) - DVP_PWR_EN --- （GPIO1_C7） 3V
->  J32 (Pin 6) - MIPI_RESET --- (GPIO0_B0)  1.8V

2.  The J32 socket is 24 PIN, 0.5mm interval, 1.5mm height, flip and low attached. It has no specific Mfg Part no.

3. FFC has also no Mfg Part #, just 24pin, 0.5mm interval FFC.
4. 1.8V standard IO voltage.

It is estimated that maximum 5V@300mA can be drawn from Pin1 of J32.

In your situation, it is best to draw current from VCC pins in the extension slot (each provides 500mA).

And it is recommended to keep the FFC cable under 15cm long.

Pin 2 and Pin 3 of J32 are just connected to GPIOs which serve as switching of CIF_PWR & DVP_PWR.
They're not power sources.

There's also no Mfg Part No of the mating connector that is to be used with the J42.

Any 2.0mm interval 4 pin connector will be fine.
