Check out the Terraria Wiki for tricks for each boss
It is recommended to BUILD AN ARENA to fight them in that is close to your home/bed for quick respawning and getting back in the fray.
It is also easiest to kill bosses with other friends in a co-op setting.
The duplicating method is easiest for obtaining the summon items or ingredients to craft them, or any weapons/armor.
Check the Leaderboards to make sure each boss has been killed and recorded, and note that Queen Bee, Brain of Cthulu, Plantera and Golem are NOT LISTED in the Leaderboards.
Note that Duke Fishron, the Pumpkin Moon, Frost Moon, or Lunar Event creatures and bosses do not count for the achievement!
Feel free to add a comment and I will credit you in the solution. :)

NOTE: if boosting, as long as you are present for the death of ANY boss and get the message "(Boss Name) has been defeated" it counts for you on the Leaderboards and for the achievement.
