Here's what I think the ratings should be
Awakened Thor: Likely
Large Island level+ (His AP should be somewhat comparable to his durability.
Instantly covered Wakanda in a storm. Battled
Hela and managed to harm her, although he was overpowered even with Valkyrie's assistance),
far higher with Stormbreaker (Sliced through an Energy Blast powered by the Six Infinity Stones, and mortally wounded
Thanos. Effortlessly decapitated Thanos afterwards)
Hela: Likely
Large Island level+ (Easily shattered Mjolnir, which was forged using a concentrated energy beam from a neutron star, at her weakest level of power, and continuously grew stronger throughout the movie as she remained in Asgard. Superior to
Valkyrie and
Awakened Thor, forcing the latter to release Surtur as a last resort)
Surtur: At least
Large Island level+, likely
higher (
Casually killed Hela and destroyed Asgard with one attack)
Odi: At least
Large Island level+, likely
higher (Fought and defeated
Surtur in his prime, taking the Eternal Flame from him and banishing him to Muspelheim. Defeated
Hela in the past and continuously maintained her prison in Hel), able to
ignore durability in some ways
I ranked Thor as "Likely" Large Island level+ because he was screaming in pain the whole time. We can't even say he was undamaged in the first few seconds because the audience can't fully see his back. Hela, on the other hand, may have overpowered Thor, but did nowhere near the same damage.
