Short answer: No. Long answer: Some forms of pencil will become obsolete, such as the #2 HB that has to be sharpened. People will just switch to #2 HB leads in mechanical pencils.
Yes, there is no rules written that you can't use mechanical pencils for school. However, it's better to get number 2 HB pencils because it's easier to erase.
Not all mechanical pencils have 2B or B lead. Some pencils have bigger lead.
I don't quite understand what you mean by HB-2 pencil but if you mean HB pencil / #2 Pencil it is not the softest pencil. Pencils scale from 9H to 9B, (HB in the middle) and 9B would the softest and darkest pencil there.

HB 2 pencil has a slightly softer lead than a regular HB pencil, which gives it darker markings. The "2" in HB 2 stands for the American grading system, while the regular HB is based on the European grading system. Both are commonly used for general writing and drawing.

Mechanical pencils, like the regular kind of pencils, use graphite.
Not necessarily. A #2 pencil may also be designated as HB. Most of the ones that you see at the grocery store or big office supply store will be number 2 (lead hardness). But I know that #3 wood pencils do exist (#3 is a harder lead). They are probably less common now, than used to be, though. Maybe at an art store or drafting supply, you might find different hardness pencils.
they are mechanical pencils
With pencils H stands for hard, B for black (soft), HB is between the two.
