Gowther kind of lacks a lot of the feats of his comrades in terms of physicality.
2) Merlin - This is... tricky to figure out. If Merlin can get some breathing room she can do a lot of extremely wild stuff, especially since her magic never stops once invoked. Sasuke has the option of Tsukiyomi and also has a good way around Perfect Cube with his telport/place switching ability should she choose to turtle up. Naruto has a harder time here simply because he lacks of the more gimmicked stuff. Personally, I'd see them both being capable of blitzing her, Merlin doesn't really have many speed feats that I think of off the top of my head.
3) Sasuke can Tsukiyomi here for the easy win. Naruto has to do it by force, which is considerably harder given what a tank Diane is. Her offensive game isn't much of a threat to him because it's various versions of "throw increasingly larger rocks," and Naruto can just blow that stuff away. It's possible she might just outlast him. Diane is functionally immortal and doesn't seem to need to eat more than once every couple of decades. Cautiously giving the edge to Naruto but this is considerably harder for him than Sasuke which I think may be a consistent thing.
4) King in terms of speed and offensive game is a whole step up than the first three. True form of Chastiefoil is abominably powerful and King can literally manipulate it from kilometres away. Sasuke will have a hard time getting any genjutsu off on him, Naruto actually might have an easier time here because his big gun factor is a bit higher. King is dangerous in that he can petrify them and any wounds he inflicts will get exponentially worse through Disaster. It's amazing how often he forgot he had that power because it was super broken. I personally think they can get through this individually but it's an extremely hard fight. The only upside is how frail King is at close range. Sasuke's teleportation will likely be his saving grace here.
5) Well, assuming non-immortal Ban here. He's kind of the master of the quickdraw with his sacred weapon as he can just steal your heart or brain from miles away almost instantly. If they can dodge that then both Naruto and Sasuke have enough gimmicks or gun to put him down before he can start draining their energy. Sasuke has the easier time here with Tsukiyomi.
6) Hahaha, oh dear. I'm not sure the lads can win this. Escanor is absurdly difficult to hurt, hits like a train and apparently is good at flatly resisting mind control which throws out Sasuke's best option. Not sure they can put him down before he hits The One and that's game right there.
7) If you can't beat Escanor then Meliodas is similarly out of your league I think. For one thing, he's ridiculously fast and his range game is ludicrous with Million Dark or whatever it was.
