'll only show scans for the stuff outside of canon for obvious reasons

I can't access the yamcha manga but here's the Soul Manipulation (Yamcha manga is in the DBH world much like every other DB media which is also explained in the fandom wiki). Whis and Vados pull the soul out of the person in the real world and swap it with yamcha's and then swap them back to their original bodies. GP scales to this.

Immortality and Self-Sustenance 1, 2 and 3 comes from the Super manga which is a timeline in Heroes.
Information Analysis is the basic xenoverse/heroes ability of checking the opponents stats

The Gods can create pocket dimensions. I don't have the scan where Whis said he made the dimension inside his staff but this is basically the same thing.
The statistics reduction is scaling from Goku, Whis and basically every other character. It is such a basic ability it wouldn't make sense if everyone could do it but the strongest couldn't.

Gods immune to 21's waves = resistance to power null, memory erasure and soul manipulation. Also scales to Goku, Vegeta and the time patrols resistance to Shrooms soul manipulation
Only scaling here is from Whis and one from Goku. GP scales to Whis because it's agreed the angles have the same abilities. The resistance to demon god magic is a God Ki user thing, not just Goku
