1. Gallade can only learn one Fighting-type move, does it make it less of a Fighting-type? Should it be paired with an other type, instead of Fighting-type? Why? - I honestly don't think so for 2 reasons. The first reason is because Gallade is not the only who does this, Combusken learns 3 Fighting type moves and only 2 of which do damage and Blaziken naturally only learns 1 Fighting type move passed Combusken, the same thing goes for Monferno and Infernape except that Monferno can learn only 2 and Infernape learns only 1 of them through level up passed Monferno. Croagunk and Pignite both only learn 1 and Toxicroak and Emboar can't learn any from level up passed their pre-evos, and Chesnaught only learns 2. Why should Gallade be considered less of a fighter than them? Second is that even though Gallade only learns one fighting type move, he also learns a few other moves that seem like something that a fighter would learn, like Psycho Cut, Fury Cutter, Slash, and False Swipe. So either way, I see him as much as a fighter than any other fighting type.
2. If it's possible to have a male Gardevoir why is it impossible for a female Gallade to exist? - I got 2 theories that may make it sound logical when combined. The first is the same as reason why there isn't a male Froslass, and what Gallade and Froslass have in common is that they both evolve by a Dawn Stone, so I have a theory that Dawn Stones, so my theory for this and for all future Pokemon who may end up getting an evolution through Dawn Stone is that Dawn Stones only work on specific genders depending on the Pokemon. The second one has to do their names. Gardevoir being a combination of either garde and devoir or garder and voir, garde and devoir being French for guard and duty while garder and voir are French for keep and see, while Gallade sounds close to Galahad which is the name of one of King Arthur's knights, so it sounds logical why Gallade is male exclusive, although I do have to question why Gardevoir's Japanese name is Sirnight.
3. Why is the Gallade line not part of Human-shape while the Medicham line is? - I'm going to guess you mean Human-like egg group because they are both in the same body shape group. In that case, I don't even know how to explain it since egg groups are weird. I mean Human-like group also has Sableye, Croagunk and Toxicroak, Hawlucha, Lucario, Pancham and Pangoro. I don't know about you, but they don't look Human like, I mean for gosh sakes, Hawlucha is a hawk, Croagunk is a toad, Lucario is a jackal, and Pancham and Pangoro are pandas. I don't see anything human like about them other than they both stand on 2 legs.
4. In which aspect Medicham is better than Gallade? And in which part worse than Gallade? - Well Medicham I think Medicham has way better egg moves it can learn, but I think it is worse when it comes to abilities as I think Gallade has better abilities even as a mega.
5. If Medicham is part of a three stages family, will it be stronger than or at least on par with Gallade? Why? - Possibly because if it did get a 3rd stage, it probably would get a lot of needed stat boosts to make it just as good as Gallade.
6. If Jynx was a stereotype for a race, how come Medicham and its Mega Evolution isn't a stereotype to the eastern culture? - I have to agree with Ketsu in that yoga is popular in western culture, maybe not as much as in eastern culture, but it is really popular in western culture.
