Official Canon is still Lucifer the Former Archangel (first and most powerfull Angel) and Beelzebub and Leviathan former Seraph class Angels...Asmodeus is unclear. If Devils, or a species near to it, were existing nobody knows. It seems Lucifer and Lilith made multiple Rituals that created the Devils we know today (my thought it he transformed all that were left from the rebellion and thex formed the first Extra Devil Houses like the Six Houses of Lucifer)

After that he used Lilith to create millions of Devils and had the strongest form the 72 Pillars. (which is written in DxD 23-25 while Hades does the same which leads to the creation of Baalberith and Verrine)
