From looking at profiles:
Mia Fey "accidentally hurt phoenix wright" which doesn't link to anything, but feels like a gag feat that gave Wright no lasting damage (her speed scaling also makes no sense)
Edgeworth has "Considered stronger than Phoenix Wright" with no actual justification
Franziska knocked out Wright, which might be fairly legit though it might've also been more through the pain of repeated whippings than actual damage, and since inflicting pain but not damage to far stronger beings is the exact purpose of whips I'd argue that doesn't scale
Simon Blackquill has his own feat (and should be) which isn't calced but seems 9-B or at a superhuman level of 9-C (breaking his handcuffs)
Manfred von Karma's justification is "Should be comparable to Phoenix Wright" once again with no justification, this is despite the fact that he's an old man
Nahyuta's justification is that his necklace can harm Wright, and he can shatter that necklace. Once again, that necklace caused pain, but seemingly little physical harm to Wright.
The Judge is 10-B, 9-C with his gavel, which I find questionable in itself as gavels aren't meant to be used as weaponry, but this isn't related.
Maya Fey "(Has injured Phoenix Wright before, forced Manfred back with a gust of wind)" Forcing someone back with a gust of wind is LS, not AP, and the other one is super-vague.
Pearl Fey (a literal 8 years old child) also has nothing more than "Capable of damaging Phoenix Wright"
Dick Gumshoe is "Superior to Jean Armstrong, who knocked out Phoenix Wright" which sounds fair enough, If that is indeed what happened.
And finally, Shelly De Killer "Casually overpowered Maya, Fought and tied with Dogen, a professional assassin, with only one arm, should be much stronger then Phoenix Wright"
Basically all of these people except potentially Nahyuta, Franziska, Shelly, Simon and Gumshoe shouldn't have their current AP ratings, and if 9-B durability is downgraded only Simon should keep it
