We can be sure. In all likelihood Azazel did see the full power of Lucifer, after all, they were direct enemies during the war and fought each other 1-on-1. In fact, if any person would know, it would be Azazel.

Also, demons are created when they rebel, fallen angels are created when they sin. Lucifer and Beelzebub were angels, but they rebelled, and became devils.

You do realize that just because Beelzebub and Lucifer were Seraphim doesn't mean anything. Azazel is a Seraphim too, as is Gabriel.

Former Seraphim Lucifer and Beelzebub created the standard, Satan-Class, which is why other Seraphim, Gabriel, and former Seraphim, Azazel, match their power. However, anything above a Seraphim in power would be stronger than any of them.

It's not like Lucifer and Beelzebub were anything special among the Seraphim. Hell, they probably weren't even stronger than Archangel Michael.

Sirzechs and Ajuka are far stronger than a Seraphim, in fact, they rank in the Top 10 strongest beings, which puts them in the same category as the Heavenly Dragons and the strongest gods of the different religion's pantheon. Lucifer and Beelzebub are nothing compared to these guys.
