Ok. Here goes:

“Which types provide the best coverage against all Pokemon, excluding the Tynamo line? (more than four types possible)”

The four best coverage types:https://pokemondb.net/pokebase/114073/what-4-moves-provide-the-most-type-coverage

Ground, Flying, Electric, and Fighting. With those four, there are only a few types that you can’t hit super-effectively:

There are a few Type COMBINATIONS that you can’t hit super-effectively:

Bug/Rock ((For Example) Armaldo, Crustle)Bug/Steel (Scizor, Durant, Forretress)Electric/Flying (Thundurus)Dark/Psychic (Malamar)Dark/Ghost (Sableye, Spiritomb)Water/Ground (Swampert, Seismitoad, Wooper)Water/Dragon (Kingdra, Palkia)

Steel Will hit Fairy, as well as Bug/Rock.Dark hits Psychic and Ghost.Ice hits Dragon and Ground, as well as Electric/Flying.

Grass kills Swampert and company, while Fairy kills the Dark/Ghost and the Dark/Psychics. Fire hits the Steel/Bug Types.

Source: PokemonDB’s type coverage checker.

In conclusion, the types you will need are:Ground,Electric,Flying,Fighting,Fire,Grass,Steel,Dark,Ice,and Fairy.

Hope this helps.

Edit: Got rid of two other possible questions, which turned out to not be the right ones.(Thanks to sumwun for correcting me instead of downvoting me.)

Edit #2: Added Steel, Dark, and Ice types to my conclusion.

It is possible to cover all existing Pokémon by having a Pokémon that can learn soak and a grass/electric type move. This even includes the tynamo line.
