Scenario 2 will be a stomp in favor of the team Naruto. Infact either of them can solo.
Scenario 1 is debatable...but I'll give it to team DMC given the Naruto team has extremely poor durability without their jutsus
You said that they have poor durability no they dont because the First Hokage was known for having a could regenerative system and Madara is immortal he could regenerate instantly and if he cant use Susanoo he could just use his Rinnegan or Sharingan. Same thing with Hashirama he could use his Wood dragon, Wood clones.
