Epic poetry tells us the story about epic heroes and their legendary quests and what supernatural events they had to go through to get to their goal. Elevated style of writing is always used to show their bravery. Thus, 1 a long journey, 2 supernatural events, 3 formal language, and 5 a hero would belong to Epic poetry.
On the other hand, 4 everyday events and 6 informal language are not the things that characterize epic poetry.
