How does this fit on a nalgene 32 oz wide mouth bottle?

It fits perfectly on Nalgene wide mouth bottles, as well as any other bottle with a 63mm mouth.

does this fit the 16 oz nalgene wide mouth bottle?

No it does not fit the 16 oz nalgene even though it is sold in a bundle with the 16 oz

Will this fit 40oz Hydroflask?

Sort of. The Hydroflask lid is designed with an insulating disk or cylinder in the middle of the threads, so when you screw the cap on, that insulation pushes the watergate down. As long a friction keeps the watergate in the position the hydroflask lid pushes it down to, it will work. But it can and may fall into the bottle if its shaken around too much.

is this dishwasher safe?

It’s made out of silicone so I would think that it is. I’ve only had washed it.
