Continuity mistake: When Rhodey, Hulk, and Rocket are trapped under the building, Rocket is stuck under some rubble but has one arm free. The other appears to be pinned to his chest. When Rhodey pries the rubble off him, both arms are by his side. (02:30:03)
Continuity mistake: Before Tony and Cap travel to 1970, Tony has a small wound on his left eyebrow which disappears.
Continuity mistake: When Tony and Pepper hug after reuniting on Earth, Pepper's hair is resting against her back. The camera changes angles and there is suddenly a huge lock of hair going over her right shoulder and down the back of it. (00:09:24)
Continuity mistake: The length of Thor's beard changes multiple times throughout the movie, and not consistent with the passage of time. For example, when talking to his mother, the beard is ~4" long, but soon after, when talking at the lake with the others about Nat's death, his beard is 7-8" long.
Continuity mistake: Before Wanda hits Thanos she has dirt on her neck then it's clean.
Continuity mistake: Just after Thanos knocks the Iron Gauntlet out of T'Challa's hand, he attempts to run over to it, but Wanda lands in front of him. T'Challa is standing in the background, a couple of meters behind her when she first lands. It then cuts to Thanos, but when it cuts to a shot panning in on Wanda, T'Challa has suddenly disappeared from the background. (02:23:10)
Continuity mistake: When Nat and Barton meet Red Skull on Vormir, Barton takes out his sword and points it at him. As Red Skull is saying their names, Barton's sword rotates itself by 90° in between shots. Note the position of the slits along the bottom and the pointed edge of the sword. (01:48:55)
Continuity mistake: When Steve is telling Sam what happened after returning the stones, Sam asks how'd that work out for him and Steve says it was beautiful. Steve is looking directly forwards at the lake when he says this. When the shot cuts, he is suddenly looking at Sam. (02:46:20)
Continuity mistake: Just after Tony hugs his father, he says "Thank you for everything", before saying "you've done for this country" whilst turning his head away from Howard. The shot then cuts to Howard Stark, where Tony's head is suddenly facing more towards him. (01:46:15)
Continuity mistake: When Tony hugs his father, he places his chin down on Howard's shoulder. It cuts to a shot of Howard Stark, where Tony does not move his head. When the shot cuts back to Tony, his head is suddenly slightly lifted off Howard's shoulder. (01:46:10)
Continuity mistake: Just after Tony returns to Earth, Pepper approaches Tony and starts to hug him. In the shot focusing on Tony, his chin is shown pressed against her shoulder, and then he lightly closes his eyes. When it cuts to a shot with Steve in the frame, Tony's eyes are more clenched shut and his face is more pressed against her shoulder. (00:09:24)
Continuity mistake: When Rocket, Hulk, and Rhodey are trapped underground, a water pipe bursts, and they nearly drown. There is a shot of the three of them with only a few inches of air left. Ant-Man comes and pulls them out, but when they reappear on the battlefield, they're dry. There was at least a few minutes between when we last saw them and when they reappear on the battlefield because Rhodey has a new suit. However, it was not enough time for them to dry completely. Hulk's hair is a little damp, but Rocket's fur is bone dry and fluffed up.
Other mistake: When the remaining Avengers confront Thanos in his compound, Bruce, in the Hulkbuster armour, pushes Thanos to the ground, and lands several meters away from where Bruce is standing. Thanos then gets punched by Bruce, who is standing directly in front of him. There are no footsteps heard of Bruce approaching Thanos before punching him. Bruce was standing a visible distance from Thanos when he pushed him and they are all standing on a wooden floor. No way would Bruce have been able to run up to Thanos without making any audible footsteps before punching him, especially with the huge Hulkbuster armour he is wearing. (00:18:10)
Answer: No, his snap simply restored all the people Thanos' snap eliminated. They discuss it before he snaps. Tony reminds him to not try to do anything other than bring the people back.
We don't know that's all he did. Considering the Ancient One's warning that removing a stone for one's universe could have disastrous affects on that universe. One would think he would return the stones.

She was talking about removing them from the timeline, nothing about destroying them. According to the comics when the stones are destroyed the powers they represent will be made physical again in a different way. This does not happen when they are removed completely, since the power inside (the energy) cannot be reassembled again.

Destroying the stones almost killed Thanos. Hulk would not have been able to bring back half the universe and the stones with no further impact.
We do know. As stated in the answer, Tony and Hulk specifically discuss ONLY bringing the people back. Since it's stated in the film, we can say with certainty that's all he did.
As stated in the film, he also tried to bring Natasha back who wasn't one of the half Thanos snapped away, so while unlikely, perhaps he did try more.
