In Pokémon Battle Revolution, friend passes are used to enable players to challenge each other in online or local battles. By exchanging friend passes, players can add each other to their friend list, allowing for easy access to battle one another. Additionally, these passes can help players track their battle records and achievements when competing against friends.
No. Any battle that is a Battle Tower or Linked battle will NOT count towards your Pokedex, unfortunately.
That depends on what Pokemon your friend uses and their movesets. Since you didn't specify this, my advice to you is to find counter-Pokemon and strategies to your friend's Pokemon. It takes more than just good Pokemon to win a battle.
