Beginning of faff
Freeza:
-1st form: 56,000
-true form: 140,000
-100% power: 210,000
Tagoma: 21,000
Sorbet: 50
(Tagoma is said to be comparable to Dodoria and Zarbon, so that's an easy one. Sorbet doesn't really do anything that would make one think he has a significant power- he was a bureaucrat. Freeza is where it gets fun. He explicitly states (after hearing that Goku and co have gotten way stronger and defeated Majin Buu) that 4 months of training will grant him a power level of 1.3 million, which he judges enough to get his revenge. Freeza's pre-training level is based on Krillin saying Goku can beat 1st form Freeza after he one-shots Recoome, and Freeza being surprised that anyone could be stronger than Captain Ginyu... even after Piccolo and Vegeta surpassed his first, second, and third forms)
Middle of faff
Freeza:
-1st form: 300,000
-true form: 750,000
-Golden form: 1,300,000
(It's never suggested at any point that his predictions were inaccurate. If anything, the opposite is implied; Goku states he raced to Earth the minute he thought he was strong enough, and didn't really go beyond that or try to boost his skills. As a result, he is at the level he said he'd be at. His first form can one-shot Gohan, his "base" is beyond everyone else but still a good bit below "base" Goku, and his Golden Form is above Goku, but not by so much that Goku can't simply outlast him. Easy peasy!)
Shisami: 30,000
Sorbet: 51
--+Green Lantern Ring: 1,000,000
(Again, Sorbet and the big guy are simple. Shisami is explicitly stated to be Zarbon or Dodoria level; I just made him transformed Zarbon level, because he's big. Sorbet again lacks any notable physical power (I assume he's trained since last time we saw him), but with his ring is able to critically wound Godku. Note that taking someone off guard alone isn't enough to injure them; you have to be close to their level to begin with. Yamcha vs Kami, Vegeta vs Freeza, and Trunks vs Buu all show this.)
Soldiers: 30-100
(The soldiers aren't all that tough. Definitely nowhere near the cream of the crop that Freeza took to Namek. They can get wasted by the likes of Roshi and Jaco. One of them gets killed by a random fish. Another dies when a cliff falls on him.)
Whis: 2,400,000
Beerus: 1,600,000
Goku: 960,000
--SSGSS: 1,200,000
Vegeta: 880,000
--SSGSS: 1,100,000
(These power levels are all extrapolated from Freeza's explicitly-stated level. Goku is weaker than Golden Freeza, but stronger than regular Freeza, and strong enough to actually beat Golden Freeza due to the latter's stamina issues. Vegeta is not far behind, but he's still behind, because he's Vegeta. Toriyama's 6/10/15 estimate easily fills in the powers for Beerus and Whis, though I also added some, errr, "gains" for Goku from Whis's trainint. Maybe Whis intentionally sabotaged Goku and Vegeta's training?.)
Gohan: 5,000
--Super Saiyan: 250,000
Piccolo: 23,000
Krillin: 250
Tenshinhan: 206
Roshi: 139
-Buff: 2,100
Jaco: 15
(Every member of the Jobber Squad can beat down the soldiers, including the guy who could only hope to fight the babies of Freeza's minions, but even Piccolo is outmatched against Shisami. Gohan takes him out in one hit, and implies he could take Freeza pre-training as well, but alas, Freeza has obtained a power level of 1.3 million by this point. None of them had a chance. On the bright side, Krillin remains the strongest Earthling, despite him and the others all dropping in power due to lack of training.)
Android 18: 18,000
Kitchen: 17,000
(As you can see, the mighty Android 18 would have been a help against the grunts, if not the Zarbon-level Shisami. However, Krillin had instead given her a more appropriate opponent...)
Yamcha: 70
(Tenshinahn deemed him too weak to come, while Jaco and Roshi actually bothered to show up. He's down to 22nd Budokai levels.)
End of faff
Mr. Buu: 26,000,000,000
(He never showed up in the movie, so I didn't change his power level from what it was last we saw him. Freeza's lucky that Buu, the voice of reason, decided to sleep through this crap.)
Kibitoshin: 5,125,000,000
Elder Kaioshin: 20,000,000
(Again; with nothing explicit to go on from them, I'm assuming their power levels haven't changed since Buu. They really were not interested in what was going on.)
