Q: 4. I have a 40.5mm lens and a 82mm nd filter, can I use a 49-82mm step up ring in between?

A: Sounds like you are planning to use two step up rings - one 40.5 to 49, and one 49 to 82. I don't know of any reason why you couldn't do this physically. I use a 40.5mm to 49mm step up ring on my a6000 using the 16-15mm lens and have not experienced any vignetting. I would think the 82 step up would be wide enough not to cause vignetting.

Q: 5. Will thisgive me a vignet if i use it on a sony 16-35mm lens and an 82mm polarizing filter?

Q: 6. If I want to go from a 37mm lens to a 77mm filter would I stack all these rings together?

A: It is possible, however I would advise you to try using as few rings as possible to avoid vignette. As well, you will need to make sure that the filter you are using is absolutely clean to avoid focusing issues.
