Okay, so other than Pikachu for his only Pokémon that he has on hand, the following is a list of Generation I Pokémon that he has currently and/or formerly officially trained and/or bonded in his entire main TV anime.

The Original Series/The Beginning Sub-Series, plus the Journeys Series

1. Ash has caught Caterpie, the one that has evolved into Metapod, and then into Butterfree, the one that he has released back into the wild so that Butterfree can mate a pink female Butterfree.
2. Ash has caught Pidgeotto, the one that has evolved into Pidgeot, the one that Ash has released back into the wild so that Pidgeot can protect a flock of Pidgey from Fearow that Ash has encountered as a Spearow until Pidgeot return in the Journeys anime series, in the Ultimate Journeys season, and in the To Be a Pokémon Master sub-season, in which Pidgeot has managed to save Ash's Pikachu's life from the Team Rocket trio, and rejoined Ash's party, keeping it at Professor Oak's Laboratory and also put it back in rotation, even though he has never Mega Evolved it for the first time.
3. Ash has caught Bulbasaur, the one that has fought and then managed to resist its evolution, so that Ash's has refused to evolve due to various reasons. Ash left Bulbasaur at Professor Oak's Laboratory and then put back in rotation.
4. Ash has caught Charmander, the one that was abandoned by its former original trainer Daminen, and also that has got disobedient by evolving into Charmeleon, and then into Charizard, and until Ash's Charizard decided that he and his Trainer Ash has all had quite enough of his disobedience for good. Ash has left his Charizard at Professor Oak's Laboratory until he has put him back in rotation, even though he has never Mega Evolved for Gigantamaxed it for the first time.
5. Ash has caught Squirtle, the one that is a leader of the Squirtle Squad, even though he and his Squirtle Squad had never evolved. Ash has left him and the rest of the Squirtle Squad, in training by the Officer Jennies, so that doesn't own Squirtle anymore.
6. Ash has caught Krabby, the one that has evolved into Kingler, the one that he has kept at Professor Oak's Laboratory until it has put in rotation, even though he has never Gigantamaxed it for the first time.
7. Ash has caught Primeape, the one that wouldn't stop its rampage like a maniac until it chilled out from this. Ash has left Primeape in training by Anthony at the P1 Grand Prix, so that Ash doesn't own it anymore, and Primeape never makes its own physical comeback in the rest of his entire original continuity main TV anime.

Ash's former official trained Lapras has grown up into adult, had become the leader of its Lapras herd, and physically returned in the To Be a Pokémon Master sub-season as being distressed by its kidnapping and abuse by those human bad guys in its memories, even the reason it never rejoin Ash's party is so that instead, Lapras decided to lead its Lapras herd again.
