Technically, god ki is stated to exude a lot of tangible pressure in episode 22 by Vegeta and episode 54 by Trunks. Thus, this explains nearly every case of a mortal seemingly being able to detect god ki when in reality, it wasn't the case, it was just the pressure they felt.
The only case that goes unexplained is Hit, because he was able to flat-out measure the multipliers of Goku's Blue Kaioken. Thus, I guess he's the exception to the rule that mortals can't sense god ki. That and just plain bad writing.
For Dende, you could argue that he's a god, thus can sense god ki, but he's not a "god" the way a Kaioshin is or Hakaishin is. So perhaps he felt that overwhelming pressure, thus his reaction. Or both.

What's the difference from God ki and "natural" God ki, which is what Goku Black used to go Rose? Why is the God ki that Goku and Vegeta have not "natural?" Is the Super Saiyan God ritual artificial?
This, I have absolutely no idea. I
guess "natural" god ki would be those who were born with it, in this case, the Shinlings (the race of the Kaioshin). Any mortal powerful enough can be trained in god ki, like Goku, Vegeta, Toppo and seemingly every other Hakaishin.

How important is God ki really for reaching these absurd tiers of power if regular ki can seemingly get you there just fine? Does Frieza's golden form let him gain access to God ki? If so, is THAT "natural" God ki? What about Hit, or Jiren? They seem to be doing just fine, if not better without it.
My
guess is that god ki is just a shortcut to reaching higher levels of power in less time than training in normal ki. In comparison to Goku and Vegeta, in Hit's case, he's lived 1000 years, so he's had plenty of time to get to the level that he's at. In the case of Freeza, I guess his race can get stronger at a faster rate than Saiyans can (4 months, wtf), so Jiren and Toppo could fall in at least one of the two categories. And there's no confirmation that Freeza has god ki. The way his aura looks isn't a valid argument, as the appearance of aura varies regardless of whether one has god ki or not.

Lastly, do you guys think, aside from the supposed power boost...does God ki have any special properties?
Like possibly cutting through hakai energy? Or do you think this could have been done by pumping out enough normal ki?

That's what I thought at first with Vegeta cutting through Toppo's Hakai. Just like in Naruto, ninjutsu couldn't affect the Ten-Tails Jinchuuriki, but senjutsu and physical attacks that were strong enough could. However, Jiren isn't confirmed to have god ki, and it's stated a Hakaishin cannot defeat him, so I guess he can pull of the same feat as Vegeta did. You just need to be stronger than the user of Hakai. Which is dumb, but whatever. And I guess a special property of god ki is Hakai, given Goku can use it in the manga and not the anime, and Hakaishin can use it whenever and wherever. Aside from that, getting stronger in a shorter amount of time and being able to sense others with god ki, I'm not sure it has any other special properties.
