Zoro jumps very high. There is no indication that he can perform skywalk.
During his training at Momoiro Island in the two-year time-skip, Sanji managed to learn the ability to use a technique similar to Geppo, known as Sky Walk.
During his time on Momoiro Island, Sanji learns a move named “Sky Walk,” which allows him to jump to great heights and to be able to float mid air by making sonic booms in the air behind him.
Actually this technique that Sanji uses is called Sky Walk it doe not use any haki, he just learned it by training while running everyday increasing his speed making him run in the air. As you can see he developed and learned this technique because of his ordeal during the time skip while training in Kamabakka Kingdom.
According to him, Zoro likes to get lost because of the Sandai Kitetsu sword. After Zoro got the sword back in Loguetown, he often got lost. Even though the sword does not have any curse like Enma, this makes Zoro lose the ability to determine direction.
It's entirely possible Mihawk noticed through their duel and training that Zoro suffers from ocular dominance in his left eye. That is to say, the left eye is stronger than the right. As a result, maybe Mihawk scarred the left eye shut and instructed Zoro not to open it until his right eye was trained enough.
Luffy can dash, jump and double-jump against cliff sides, extend his arm to leap to high ledges, and even swing around cities like Spider-Man.
When using Gear 4, Monkey D. Luffy is capable of jumping off the air, akin to Geppo, by utilizing the extreme compression of his rubbery body.
After the events of Wano, Sanji was given a bounty of 1.032 billion berries and that is nothing short of staggering. This came on the back of him awakening his exoskeleton and the latent Germa abilities that he had inside himself, allowing him to take down Queen the Plague of the Beast Pirates.
So far, it is unknown how Sanji is able to light his legs up on fire. According to Oda, it is the burning passion of his heart that enables him to do so, and Sani has himself claimed that his flames burn hotter than any other flame simply because his passion is limitless.

The fact that Nami lets Sanji smoke in her body says quite a lot despite it being a small gesture. She knows Sanji needs to smoke to relieve stress, and she lets him do it despite it not being good for her own body.
Gan Fall is the current, two-time God of Skypiea, having been usurped once by Enel. During Enel's reign as God, Gan Fall worked as a mercenary and called himself the Knight of the Sky. He is an ally of the Straw Hat Pirates during the Skypiea Arc.
King ate the Ryu-Ryu no Mi, Model: Pteranodon, which allows him to become a Pteranodon hybrid or full Pteranodon at will. It also gives him the ability to fly and perform powerful aerial attacks, as seen when he was able to knock down the Queen Mama Chanter and throw Big Mom in the sea.
Enel is a Birkan who occupied the seat of God at Skypiea. Being one of the strongest characters in the sky, Enel possesses the ability to use Observation Haki, although up there, it is known as 'Mantra'.
When he was a child, he was afraid when Garp would find out about his dreams of sailing as a pirate. He is wary of Nami's temper, as he thought whoever wanted to marry her is brave.
Since Luffy's Devil Fruit is actually a Mythical Zoan instead of a Paramecia, it granted him a completely new transformation instead and typical of Luffy, he ended up naming it Gear 5. In this form, Luffy gains a completely white transformation and takes on an appearance similar to that of the "Sun God" Nika.
Gear 5 is even considered to be the peak form of Luffy, unlike any other we have seen before. Gear 5 is Luffy's pinnacle power, and he can do anything he wants in this form. Furthermore, it is mentioned that his powers are only limited by his imagination.
Although like others who have eaten a Devil Fruit, Luffy cannot swim; when he is submerged in water or contacts the Sea-Prism Stone, he loses his strength and cannot move on his own. In addition to his Devil Fruit powers, he has immense strength, durability, speed, reflexes, agility, endurance, and stamina.
Using Gear 4 has a number of drawbacks for Luffy. There is a limit to how long he can keep Gear 4 active, as noted by both Luffy himself and Doflamingo. Once this limit is reached, Gear 4 automatically deactivates, leaving Luffy exhausted and barely able to move.
Using this martial art, Sanji can easily overpower numerous enemies simultaneously, including pirates, Marines, and World Government agents. While running away from the okama on Momoiro Island during the timeskip, he discovered how to walk on air, allowing him to attack from above and evade incoming enemies.
Prior to One Piece's timeskip, Zoro's left eye was fully functioning and completely uninjured. Yet when the Straw Hats reunited after their respective adventures, Zoro's left eye was mysteriously scarred shut. Prior to the timeskip, his left eye had been seen glowing when using certain attacks.
No, it's just a nickname Sanji gave to make fun of him.
It was most likely lost by Mihawks little knife thing. Zoro pretty much did it to himself.
