So, this is how I envision the profiles looking (I will likely replace everything with the correct scans) when or if it's all accepted:
Thor: At least Multi-Solar System level, likely Low Multiverse level (His first fight with the World Serpent shook all Nine Realms. Splintered the World Tree, a construct that transcends time and space in all of the realms and contains them within its branches, in his second fight with the Serpent. Fought evenly with the Fire Giant Surtr, who created all the stars in all the realms and is prophesized to destroy all nine realms in Ragnarok and actually destroyed them in the World Serpent's future)
Kratos: At least Multi-Solar System level, likely Low Multiverse level (Consistently defeats Baldur, who is able to fight and knock out the World Serpent. His Leviathan Axe is stated to be equal in power to Thor's Mjolnir. The Blades of Chaos, which infuse Kratos with their power when used, are stated to be much more powerful than the Leviathan Axe and Mjolnir by Brok. Can close Realm Tears, which are stated to threaten the fabric of any given realms, with his bare hands)
Baldur: At least Multi-Solar System level, likely Low Multiverse level (Knocked out the World Serpent and consistently fights evenly with Kratos)
I am very uncertain if Atreus is actually scalable considering the whole shtick is that he lands a hit and proceeds to get pretty much steamrolled. Did he ever truly fight anyone?
