My major is Japanese
It means "What page [is it]?"
Nansai desu ka? Means what year is/was it? Nan=what Sai=year Desu=to be(is/was) Ka=questions particle. Its literal translation is "what year is?" the subject that you are talking about is implied by the context of the conversation.

You misspelled that, but from what I'm interpreting, it means "What is your favorite animal?"
To ask someone's name in Japanese, you can say "ใๅๅใฏไฝใงใใ๏ผ" (O-namae wa nan desu ka?). This translates to "What is your name?" in English.

The answer is Nani or 何"nani?" or "nan desu ka?"

You may say 'Nan peeji (desu ka).'
Onamae WA nan desu ka?
I'm going to assume you meant "onamae wa daisuki" Which means 'I love your name'. OVER-EDIT: Or, unless the person meant "o-namae wa desu ka" or something like that, they were asking "Your name?" or like "What's your name?" or something along those lines
