You can give the Upgrade to Porygon and then trade it to a friend to make Porygon evolve into Porygon2, in order to evolve Porygon2 then give a Dubious Disc to Porygon2 and then trade it to someone and it'll evolve into a Porygon-Z.

Catch pokemon, battle, almost all the same stuff as the other games.
You can use Upgrade to evolve your Porygon into Porygon 2. To do this. Make your Porygon hold the Upgrade in a trade. (This will only work if trading it to a G/S or newer game.)
Vileplume does not evolve.
Use the dubious disk to evolve Porygon or Porygon2 to Porygon Z

No.

Yes, you can evolve Porygon in Pokémon Mysery Dungeon: Red Rescue Team but only into Porygon2, Porygon2 cannot evolve into Porygon-Z. You wil need to take your Porygon to Luminous Cave and it wil evolve as long as you have the Upgrade item and the Link Cable item.
