If the Marvel Team pooled their power together, which I'm sure they could easily do, I'd say they have every chance of clearing the gauntlet. Won't be that difficult, and they should walk away with some wounds.
Welcome to the Vine. Be sure to read the forum rules about posting spite battles. Because this is exactly what a spite battle is. Judge Dredd has nothing in his inventory or repertoire of abilities that could help him in any scenario against Spawn.
Why do people keep using Superman Prime One Million? He has no feats that'll give him any sort of victory in any sort of battle. Zoom loses to the first two Supermen, but wins against the 3rd. As for Round Two, alongside Flash, both lose to the first two Supermen but win hardcore against SPOM.
