Majority of those things, piccolo can do. Matter manipulate, change his size and structure... dbz characters can become intangible as well which was shown when burta and jeice was fighting goku...astral plane, I agree with, making goku calm... naah, that's not working. Babidi was more powerful than his fatherand his father created a universal threat, buu. Well babadi couldn't even take control of vegeta but he was able to mind wipe someone like dabora who is more powerful than cell, a solar system buster... so naah, I don't think mental attacks will work.
I don't think some of those things would work.
