>First Partner PokémonThat one's true, although the term "Starter" has been used multiple times in the games as well, notably in BW.
>Special Pokémon"Special Pokémon" is an official term, but it means something else: these are the Pokémon restricted or banned from some official tournaments. All of them are Legendary or Mythical, however the inverse isn't true: Zapdos, for example, is a Legendary, but not a Special.
>Late BloomerThis term was only used once as a name for the merch line. Pseudo-Legendaries haven't been officially acknowledged with a proper umbrella term, and probably never will.
>Different Coloured PokémonThe official English term is, in fact, "Shiny". See the description of the Shiny Charm, or Jacq's dialogue.
>FriendThat is simply not true, but not outside the realm of possibility.
>Foe>Townsfolk/CityfolkI have never seen these terms used officially.
>Pokémon LeaderThis term was used by some early manuals. "Gym Leader" is an official term as of SV.
>League Champion or Pokémon ChampionThe term I remember seeing the most is "Pokémon League Champion", but this is mostly correct. The term "Champion" is still being used, however.
>Pokémon ExpertThat's just the Japanese name. In the English-language canon "Pokémon Professor" is correct as of SV and Horizons.
