No aliens are known to exist, so your question is unanswerable.
No, they are human.
they are not aliens, they are superheros with a human host in their spirit. All the ultramans come from Japan.
If human, Foreigners, if from other worlds- Extra-terrestrials. Aliens is a bad term as it has political overtones ( Illegal Aliens, for example)
'Aliens' are real. In any given country, a foreigner may be described as an Alien.
No there not and aliens maybe not real.
No. Aliens are people from another country who have retained their citizenship in the other country. Aliens as entities from outer space have not been shown to exist.

No human would know.
