All of these are correct
the teacher and the learner were in the same room.

That sounds like an excellent science experiment! You should totally do that and measure the height in inches or centimeters with a yardstick.
If they are dropped in a totally controlled manner then they would land in the same spot. However, if dropped by hand, there will be minor differences in the positions of the hand which will affect the outcomes.
It is doubtful that Newton ever visited Italy. Galileo Galilei is the one who 'apparently' dropped the balls of the tower and this may or may not of happened but it certainly was not a scientific experiment due to the errors involved (no stopwatch, air viscosity etc.) If it did happen it would be a simple visual representation of the theory.

Torricelli's experiment: Spring 1644, Florence (Italy): Venue of a famous experiment: Torricelli did his experiment with quicksilver or mercury. He proved two things with this experiment: 1, Nature doesn't abhor the void (nature doesn't fear vacuum) 2, and that the air has weight: He used a glass barometric tube of about 1 m in length which was open at one end and closed at the other end. He also used a glass funnel, which was used to pour in mercury. He put the glass funnel inside the one end open glass barometric tube of 1m and poured mercury into it. He used this method to avoid the formation of any air bubbles inside or in other words, it was not to create any void inside the tube. He removed the glass funnel after pouring the mercury, and then closed one end of the barometric tube with his finger, inverted it to make the open end at the bottom and the tube was inserted into a vessel containing mercury carefully without forming any air bubbles. He found that the mercury in the 100cm tube dropped to 76cm. He did the same experiment with water. But that required a long tube. Water has a density 136 times less than that of mercury, and this experiment returned the water column at a height of 103m. This means that the height of the water column = the height of the mercury column (76cm) X relative density of water with respect to mercury (136).
All of these are correct
It depends what the weight reading was originally measuring. If it was measuring the weight of the experimenter and the rock they were holding, and the water is not being held by them, then the weight will decrease by the weight of the rock. If it was measuring the weight of the water into which the rock it dropped, then it will increase by the weight of the rock. If it was measuring the weight of something totally unrelated to the experiment, then dropping the rock will have no measurable effect on the reading of the weight. Context needs to be given for the weight reading for a proper answer to be given.
There is no evidence, the bomb was dropped as a war weapon.
In his gravity experiment Galileo dropped objects form the Leaning Tower of Pisa, in Italy.
as done in Galileo's experiment when he dropped a large rock and a feather from a tall tower both hit the ground at the same moment when dropped from the same height.
Galileo and not Newton conducted the experiment at the leaning tower of Pisa. He took a large weight and a small weight and dropped them at the same time. They fell at the same speed and landed together.
That man would be Galileo Galilei, and he was from Italy.
Galileo Galilei; leaning tower of Pisa.
I wasn't there, so I have no knowledge of how things were set up in that particular experiment. The only force I'm sure of is the force of gravity, and your use of the term "dropped" seems to confirm that assumption.
WILCO is a Military term meaning WILl COoperate Negative, negative. "WILl COmply." Later dropped because use of "Roger" to indicate receipt of orders conclusively implied compliance.
No, it is not! I tested and did a science experiment with agar plates and your food gets contamnated when dropped on the floor for 5 seconds or longer.
This is an old experiment. Neither. Both balls have the same velocity as gravity draws on them equally.
