He's got to be quite a bit above the others, besides Quitela, Champa, and perhaps Mosco. We know at the start of the ToP arc, he said it would take Vegeta a million years to become his rival at the rate he was improving, which is an obvious exaggeration, but still implying it would take a long time to get that powerful. Vegeta has improved drastically since then, but the Moro arc in general was fairly vague with its power increases, so it's hard to tell just how much stronger he's gotten. I'm guessing at least 2-3x in order for his SSBE form to be stronger than UI Omen Goku currently, who was stronger than he was in the tourney.
UI Goku (ToP) > Jiren (limits broken) > Jiren > UI Omen Goku (ToP) > Jiren (powered up) > Jiren (relaxed) > SSBE Vegeta (ToP) > Kaio-ken CSSB Goku (ToP) > Gohan (ToP) > CSSB Goku (ToP) = CSSB Vegeta (ToP)
If we consider Broly as a whole (marketing material and the movie), he's probably around ToP UI Goku's level. Current Vegeta is bare minimum stronger than that, and Beerus is even stronger than that.
Beerus > SSBE Vegeta > SSJFP Broly >?< UI Goku (ToP) > Jiren (limits broken) > Jiren > Belmod >?< UI Omen Goku (ToP) > Jiren (powered up) > Jiren (relaxed) > SSBE Vegeta (ToP) > Kaio-ken CSSB Goku (ToP) > Gohan (ToP) > CSSB Goku (ToP) = CSSB Vegeta (ToP)
We also don't know just how much stronger Jiren is than Belmod. Either way, Belmod's probably within one-shot range of Beerus judging by how strong everyone is now compared to regular Jiren.
