All are correct. Actually counting in Japanese in much more complicated than that, as there are dozens of counters. If you want to say "one", it could be : hitori (for people), ippiki (for some animals), ippon (long objects, bottles...), itchimai (falt things, pages...), issatsu (books), etc.
So for "4" in your list, you can say "yonin" (4 people), yonhon, yonmai, but shigatsu (month 4= April), etc. depedning on the counter.
To make things worse, Japanese often invent new pronuciation for numbers in ads on TV to make them easier to remember or more musical. So 0 can be read as "maru" (round), and 1717 could become "iina iina" (short for "itchi nana", but phonetically it means, "so good, so good"). Sometimes they say any number in English.
Maybe you should have a look at this site to learn some Japanese :

Or buy a book like "Japanese in 3 months" or basic grammar. They should explain the countig system.
