Six channels but I would expect those to be multiplexed into one ADC convertor where the OP is looking for multiple simultaneous conversions.Frankly I'd use an Arduino, which has six 10-bit ADC channels on board.
I expect most microcontrollers will be the same because genuinely simultaneous conversion is so rarely needed it doesn't make sense to have more than one convertor.
I would have thought the RP2350B, with its ability to round robin sample using DMA, would be ideal for the job if its resolution is good enough and sample rate fast enough which I believe it would be. You should be able to take the arrays of samples and then extrapolate each channel to what they would have been at a simultaneous point in time without being too inaccurate.
