Answer 2

Is the order of acquisition the same among the the speakers of the same language who acquired it as native language? No. Think about babies and very young children. They are all listening to everything that goes on around them, but (as I've learned) they are paying closest attention to their parents and siblings, if there are any. Some young children start speaking single words as early as a few months, and maybe full sentences around 10-12 months, but others do so later, sometimes much later. Why do you think there are such differences?

How is it related to the speed of acquisition? What do you mean by "it"?

ıs it the same among the people who acquire it as a foreign or second language? Learning a second (and third, etc.) language is often done in school; the order of acquisition may be different from learning their first language. Then there are the children who learn more than one language from birth, depending on who lives in the same household. Everyone is different; I doubt there are any hard-and-fast timelines.

How is the speed of acquisition among these people? I don't understand this question.
