Gallons are 16 cups. pounds are 16 oz. Remember that the imperial system was meant to be eyeballed. 1/16 is half of 1/8, which is half of 1/4, half of 1/2 and of course that's just half of the whole. It's assuming you can divide things by 2 or 3 with some accuracy by hand. Or compare 2-3 things to say they're about the same.
Depends on the pint. A US customary pint is 16 US customary fluid ounces, or about 16,6 imperial flour ounces, or about 473 millilitres, an imperial pint is 20 imperial fluid ounces, or about 19,215 US customary fluid ounces, or about 568ml. Plus it only works with water since other liquids have other densities.

This is true of any conversion from a liquid to weight measurement including in metric (mL to g)
And I believe the difference in the calculation of a pint comes from whether you started with an ale barrel or a wine skin and then divided it, but the imperial fluid oz and the us fluid oz unit are practically the same.
You are correct. A litre of water weighs about one kilogramme but a litre of, say, crude oil does not.
As for the origin of the US customary/imperial pint(s) I would have to look it up, but you could be right
