Escanor annihilates everyone. The end.

But seriously, assuming everyone is at full power, here is how it goes.

Meliodas vs Ban: Meliodas (with great difficulty)

King vs Elizabeth: King (handily)

Merlin vs Arthur: Merlin (moderately)

Gilthunder vs Gowther: Gilthunder (barely)

Escanor vs Diane: Escanor (one-shot)

So you have a slightly tired Merlin, and very weakened Meiodas and a almost full powered King vs a very weak Gilthunder and full power Escanor.

Escanor defeats King and Merlin easily, then he and Gilthunder defeat Meliodas. I mean, unlike DBZ, power levels do actually matter in this world, and Escanor dwarfs everyone, even Meliodas at full power. Of course, this entire battle hinges on the battle happening during the day, but since Merlin is Escanor's sun (apparently) and he now utilizes the power of boner to activate Sunrise, that really isn't even a limit. In a full out battle royale, same thing; Escanor is just too powerful. Look at the power levels. Meliodas has about 32,500 and Escanor has 50,000,
