Well let's see...
1) First off, I was not necesary talking about the chances of thenformation of life, but rather about the probability of aliens being humanoid. With that said, I will put all of your examples in my context.
Second off, when you said that thenorbit has to be exact, I think you were refering at the planet being in the habitable zone. And yes, that is one of the main conditions, but as I said: planets being in the habitable zone are not that uncommon. Look at the closest exoplanet of the Solis Solar System: Proxima Centauri b. She is right in the habitable zone of its star, Proxima Centauri. Hell, look at our Solar System itself: there are not one, not two, but three planets in the habitable zone (Venus, Earth and Mars).
2) The gravity doesn't play an important role in the formation of life. Yes, a planet needs gravity to sustain life, but as soon as the bosy we are talking about can at least be clasified as a moon, then it automatically has a gravitational field strong enough to attract a human that is jumping on its surface.
And before you say something in the lines of "the gravity needs to be like ours", let me tell you that you are wrong. Every body from our SS has a very different gravity compared to the Earth's. The one with the closest gravitation attraction might be Venus, due to it being a little bit smaller a d as de se as Earth. Studies show that if a human colony would be made on another celestial body, the spines of the humans would either elongate or condensate to better suit the gravity. In other words, we would adapt. So would the life forms that would evolve on different planets.
3) The... Materials? I mean yes, life as we know it cannot form in gas giants,but I think that was obvious.
4) OK, here you are right. A planet needs to have a proper atmosphers. Unless we are talking about beings that don't need air to survive.
5) The distance? See point number one.
6) The moons literally don't play any role.
7) Location from its sun? See 1) and 5).
8) Location from its stars? Uhm... See 1), 5) and 7).
9) The weather mostly results from the atmosphere.
10) The air also results from the atmosphere.
11) The ground, aka 3).
12) We have proofs on our own planet that the humidity is not that important. There are things like reptiles and amphibians.
13) Electricity literally has no role here.
14) And neither do the surrounding planets.
