and also

the "9" is the style I like very much, I really wanna know what font it is

Most probably custom designed. From the FAQ:

And logos of sports teams?
There you have to keep in mind that sports merchandising -- everything from baseball caps to soccer jerseys -- is big business, so the popular sports teams have every reason to make their logo as difficult to imitate as possible. Most of them are custom designed or use heavily customized existing fonts.

I see! I asked this because I read a feature here
http://www.linotype.com/2710/footbaljerseyfonts.html
and learnt that so many jersey typefaces are based heavily on existing fonts. so I was wondering if these are the same cases. :)
