Eevee Who Need Evolving

My first journal for 2018, and I need some help from "experts," so to speak. See, I have a total of eight Eevee in my Pokémon Ultra Sun game, seven of whom I'd like to evolve for the Pokédex. However, I want to make sure I choose the right evolution for each Eevee, so I'm enlisting your help. Below are each Eevee, their genders, and their natures. Let me know who should evolve into who in the comments below. Please note that I don't need Sylveon; he's on the team I used to beat the game. The Eevee left over will remain as such.

Eevee 1:
Gender: ♂ Male
Nature: Mild

Eevee 2:
Gender: ♂ Male
Nature: Naive

Eevee 3:
Gender: ♀ Female
Nature: Hardy

Eevee 4:
Gender: ♀ Female
Nature: Naive

Eevee 5:
Gender: ♂ Male
Nature: Brave

Eevee 6:
Gender: ♂ Male
Nature: Bashful

Eevee 7:
Gender: ♂ Male
Nature: Timid

Eevee 8:
Gender: ♀ Female
