For Delta Venusaur I’d recommend using Calm Mind, Moonblast, Psychic and Moonlight.
For Haxorus I’d replace Taunt with Earthquake, you can get the TM for it in Victory Road before the E4.
For Typlosion you should replace Swift with Extrasensory and Will-o-wisp with either Focus Blast or Hidden Power depending on what type it ends up as, Electric or Grass would be a must have, if its neither of those then Focus Blast is probably better.
For Delta Metagross you might want to replace Toxic with Rock Slide but if you end up going for a more defensive version of it then you could run Toxic/Stealth Rock/Sticky Web/Earthquake instead.

And for Feraligatr I’d personally recommend changing it for a different Water type entirely but if you want to use it then the moveset you’re planning is fine, but consider using Dragon Dance over Swords Dance.
