This thread has quickly become a wrecked tangle.
The only humanoids that are meant to look human are humans.
The outer resemblance is not the deciding factor. It is more the inner structure that provides the "humanoid" feature. So it is an upright movement on two legs, but also the general physis, like having two arms (or more), hands (with opposing thumbs, number of fingers), the general sceletal structure of a man. Having a language for communication and culture, is another part of the concept. In any case it is a very broad definition and not all have to apply.
So, the outer resemblance can vary much more greatly. A humanoid can have human skin, a metallic or stone-based skin, feathers, fur or scales. It can have wings, and even more arms, can vary greatly in size and also stature. It can live underwater, in the darkness or up in the air, technically they can even be undead or inanimate or machines.
So much for the pseudo-scientific definition, as we do not really have or need to define it, since there are no other things yet (apart from some robots) that would qualify. In that regard the standard mech of Battletech or Pacific Rim is humanoid, yet the robots from AI are mostly android (which means man-like). So this is more the word you might look for if you want to refer to other beings that do look like humans.
Most franchises and universes also choose or modify their own definitions.
