Arrows are no big deal to Wolverine. Green Arrow would switch to trick arrows, but those would just anger Wolverine and he would close the distance quickly, making short work of Green Arrow.
Wolverine is literally an unstoppable killing machine when versus the green arrow. Even with ample prep time green arrow wouldn't have a chance wolverines healing factor means that he can carry on fighting for several days without fatigue.
Green Lantern can protect himself pretty much indefinitely against Wolverine's claw strikes and his ring allows him way too many offensive options for Wolverine to overcome. It might take a bit because of Wolverine's healing factor, but eventually, Green Lantern is going to take him down.
Magneto may not be impervious to harm like Wolverine, but he has an obvious advantage over him; Magneto can control and manipulate all metals even if there's only a small trace of them. On many occasions, in both the comics and the films, Magneto has used his powers to beat Wolverine.
Wolverine was one of these heroes. Wolverine ran in with his usual ferocity and got the drop on Thanos, hitting him with all six claws in the chest. Without the Gauntlet, this may have hurt Thanos. With it, it was a meaningless attack.
His adamantium claws are one of the few weapons in the Marvel Universe that can consistently pierce Hulk's skin and Wolverine has no problem going for Hulk's head. In fact, if it came down to it, Wolverine could cut Hulk's head off, ending the Hulk once and for all.
In Marvel Comics, Thanos is an ultimate villain who needs no introduction, but when it comes to DC Comics powerhouses, the Green Lantern Corps is a group of beings who are so powerful that they could easily stop Thanos dead in his tracks.
However, the Flash has survived worse circumstances than fighting Wolverine, so it is safe to say that if the Flash stayed focused and realigned Wolverine's atoms to turn him into a living magnet, then he would be able to beat him in the most humiliating way possible.
The healing factor is Deadpool's biggest advantage and that's what is going to give him the win. Green Arrow has some devastating trick arrows but none of them are going to be enough. Ollie's going to get gradually more and more frustrated that Deadpool won't stay down, which is going to give Deadpool an advantage.
Green Arrow is, more or less, the best archer in the entire DC Universe. Unfortunately, he doesn't have the tools needed to take down a powerhouse like Black Adam. Given that Green Arrow has no powers, just a quiver full of arrows, it's unlikely that he could defeat someone as strong as Black Adam.
Despite all of his skills, Spider-Man would be able to beat the Green Arrow because of his superior agility and instincts. Spider-Man would be able to dodge any arrows using his spider senses and then be able to subdue Oliver Queen with his web-slinging and acrobatics.
We're talking about the Immortal Hulk -- the Breaker of Worlds. If Ollie was up against the Hulk of the past, the one who had the brain of a child, Green Arrow would probably beat him pretty quick through stealth and trickery.
Hurting the Hulk would be hard for the Flash, especially since every missed attack would make the Hulk angrier. However, the Flash can always deploy the infinite mass punch, his most devastating attack. It would be a last resort but it would give the Flash the win.
While it is fairly obvious that the Flash could run circles around Thanos under normal circumstances as his powers make him virtually untouchable, there wouldn't be much the Scarlet Speedster could do if he was around for Thanos' Infinity Snap as there is no way to outrun the god-like power of cosmic chance.
Flash wouldn't really be able to hurt the Juggernaut with any of his attacks and at first, Juggernaut wouldn't be able to hit the Flash. However, at some point, the two men would end up running at each other and, well, nothing stops the Juggernaut.
As it stands, Batman alone is helpless against cosmic level threats, much less against Thanos. Really, the best thing he could do is to ask for the Hellbat armor from the Justice League so he can survive Thanos' physical attacks. Even then, he'll still lose.
Loki's a born trickster and knows how to manipulate his foes. Hal Jordan's headstrong nature will make him easy for Loki to trap and use his powerful magic to ruin Green Lantern's day. Jordan just isn't used to battling someone like Loki. He'll try to do what he always does, which will cost him.
Hal Jordan, a.k.a. The Green Lantern, is a very powerful superhero. He has one of, if not the, strongest wills in the galaxy. As a result, he overmatches many of his foes when he has his ring on. Although Batman is one of the most dangerous people/heroes on Earth, Green Lantern would beat Batman in a fight.
Wolverine has less experience than Thor, but is a better martial artist. However, that wouldn't make much of a difference. Thor can fly and has Mjolnir at his disposal, giving him options for long range attacks Wolverine can't match. Wolverine is too smart to go against the God of Thunder alone.
The two brawlers have fought beyond these two encounters, but these two fights establish a few hard facts: the Hulk can be overpowered by the Juggernaut; the Hulk cannot consistently stop the Juggernaut; and most importantly, the Hulk's strength, even at maximum, cannot harm the Juggernaut at his maximum power.
