Hello Teo,
There have been discussions about "high" and "tall" in here before.
Generally, "how high" refers to the height at which something exists.
How high is the TOP of the mountain?
How high is the TOP of the building?
How high is the shelf in your kitchen?
Generally, "how tall" refers to the measurement. So, 1,2, and 3 are correct. 4, 5, 6 are not,
