Hello
I am considering using STM32F769NI.
Can all GPIO pins measure analog voltage when set to input?
Thank you.

That depends on your interpretation.
The interpret the voltage on the input pin as binary signal (0 or 1 / L or H), using the threshold (datasheet) as reference.
A voltage can only measure pins with can function as ADC inputs (pin multiplexing). Again, check the datasheet.

No, only pins connected to the ADC can read an analog voltage. The rest read digital only.
