This is a bit of a tricky match since none of these guys are top tier Godzilla fighters. That being said, I would give the edge to Ebirah. That’s a decently controversial move, but Ebirah can really do some damage with his pincers. Kumonga’s arms aren’t enough to counter that and he’s in no position to dodge Ebirah’s strikes. Only his web would have helped and it won’t slow Ebirah down. Ebirah wins.
