Assuming this the current versions in all cases...
Etrigan << Sinestro - The latter survived a planet exploding. The former has nothing approaching that and would be vaporized.
Kain>>> Lobo. Kain can't die by conventional means. He'll literally eat Lobo.
First Born =/ H'el. Born beat-up Orion and WW. Orion fought Superman evenly. So Born is stronger/ more durable. Not to mention holding open the boom tube and tanking atomization. H'el has a bunch of powers Born has yet to show a counter to..so. H'el wins. H'el also way faster.
Graves=/ Atrocitus- Red lantern light should penetrate his shielding, and Atrocitus has experience reliving his past and saying **** off.
Enchantres<<<Helspont. Too versatile and powerful.
Adam<<<<<<<<<<<<<<<<<<<<<<< Invictus. Adam has shit feats, but even at his old levels Invictus probably wins.
Team two obliterates.
