How were timezones fixed by countries? Why did some countries get 3 timezones and some get only 1 despite being the same size? How did we get all the countries to measure time globally using the same measurement?

The countries decided for themselves. Timezones aren’t some internationally regulated thing: Every country can literally declare what timezone they are on (or fractions thereof) at any time.
> Why did some countries get 3 timezones but some 1
Because some countries decided to use three to follow the geography of the country, but some decided 1 was plenty to have the entire country follow the same timezone regardless of location.

Trains and business. In a rapidly interconnected world where communications were getting faster and faster synchronizing clocks between interacting countries (or between communities within countries) became a smarter and smarter decision.
