Other mistake: Scott arrives in the park and sees hundreds of memorials listing people who were killed by Thanos. In the first close-up shot shown of one of the memorials, the name Norbert Lamey can be seen five rows from the top on the right hand side. The camera then pans to Scott walking in front of the memorial to the right of it. The name Norbert Lamey can be seen repeated on the opposite side of the memorial Scott stands in front of. (00:24:25)
Other mistake: When Thanos gets pushed over by Bruce, he is shown turning his head to the right whilst on the ground and tells the Avengers they should be grateful. Whilst Thanos was being pushed over in the previous shot, all of the Avengers in the room were shown standing several meters in front of him. If Thanos was lying on the ground with the Avengers standing several meters ahead of him and he was looking to his right, then he would have been looking at the wall and not the Avengers. (00:18:10)
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.
