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.
He's powerful but not invincible, and there are ways to stop him. Hal Jordan, on the other hand, did not need any of these means to beat Superman. Instead, he uses the pure strength of the Green Lantern Corps, proving that a Green Lantern alone is powerful enough to defeat Superman.
As one of the few Green Lantern weaknesses, Captain Marvel's energy blast would theoretically be powerful enough to both weaken and break through his constructs, making her the more likely victor in a confrontation between the two.
One of the most powerful heroes in the entire DC universe is the order of Green Lanterns, made up of beings possessing great willpower who are chosen to join the ranks of the Corps by the Guardians. Green Lanterns are capable of fantastic feats while wielding a Green Lantern ring.
That depends on how they fight. If the Lanterns fights by Hulks rules in a straight up fight, then the Hulk will win, but if the Lantern is clever and uses his brain to out think and avoid Hulk, the Lantern has a good chance of winning.
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.
Superman is widely regarded to be one of the most powerful beings in the universe, but he has a variety of weaknesses, like Kryptonite, red sunlight, and magic. Which means that of all the Green Lanterns, Alan Scott is the best equipped to defeat him in a fight.
There is no clear answer as to who would win in a fight between Green Lantern and Thor, as both are incredibly powerful superheroes. However, if it came down to it, Thor would likely have the advantage, due to his ability to control the weather and his powerful hammer Mjolnir.
The color yellow is Green Lantern's primary weakness, but he was able to use it to save the Justice League. In 1960's Brave and the Bold #30, the Justice League confronts the android Amazo for the first time.
Realizing that, as a visual artist, Kyle relied on his eyes to both draw and focus the energies of his ring, Batman decided the best way to neutralize Green Lantern was to blind him. As Kyle was too powerful to blind through conventional means, however, Batman came up with a plan to use his own ring against him.
Green Lantern can create force fields easily so Spider-Man can't even touch him with his hands or webbing. Green Lantern can also shoot energy beams completely decimating Spidey or at least cutting his webbing to where he falls to the ground.
Even so, taking both heroes at their maximum potential, it's practically a given that Superman would overpower Thor in terms of sheer physical strength. He may not consider himself a god, but the Last Son of Krypton can still outmatch the God of Thunder on his best day.

Even though Superman is often considered the most powerful character in the DC Universe, Shazam definitely comes close, and he can even beat the Man of Steel. And with a massive power upgrade, there's no question that Shazam can meet Superman blow for blow—despite the upgrade's terrible side effects.
However, with Wade Wilson's long history of taking down physically superior opponents with a disarming quip and well-placed bullet, Deadpool would be no slouch squaring off against even the greatest Green Lantern of them all.
Technically, yes. Realistically, no. They'd be able to easily create a simulacrum of Mjolnir absolutely no problem. Generating a construct that resembles Mjolnir would be child's play to even a rookie member of the Green Lantern Corps.
No Green Lantern will see the light of day against Doomsday… Doomsday is a walking monster, one that can casually contend with the likes of Superman and various other powerhouses. Not to mention that Doomsday can adapt to practically any and all that Green Lantern can muster.
