Kami did have a bad vibe about him, but unlikely that it's power related. Since he was above all of the Super Saiyans after absorbing the humans of Gingertown, I'd place him somewhere around the Super Saiyans before absorbing, so he'll still be more than enough to handle #19 in battle.
It looks like Cell was stronger than Trunks or Vegeta ever since the beggining

Trunks: “I feel another stupendous ki…! There’s someone else!! Someone else I don’t know!!”
Kuririn: “It’s Piccolo!!!”
Note: so in other words, Trunks considers both Cell and Piccolo’s ki as ‘stupendous’.

Vegeta: “One of those guys with mysterious, absurdly large battle powers has vanished…But the other one remains…”
Context: the vanished one is Cell, and the remaining one is Piccolo
But this really isn't surprising, like you said we should expect him to be at least at the level of a Super Saiyan to begin with.

I would doubt they are stronger than Freeza.
Freeza still was mentioned a few times, so I wouldn't expect him to be completed out-classed. No.19 and 20 on the other hand, they made jokes about their strength, and how they are not as strong as they were meant to be.
Besides No.20 was completely trashed by Piccolo, there was a huge difference beetween their powers. And No.20 is supposed to be much stronger than No.19, so...
Of course Freeza was clueless in many instances during his battle with Goku and the others, so it's not impossible that No.19 would end up absorbing all of his energy.
