Question

" nanda yo "  what does it mean ?
i heard this word form " yamato nadeshiko shichi henge Anime "  , the sentence is " busu wa kirai nanda yo "?
busu = ugly
kirai = hate
the problem is that the sentence doesn't make any sense to me ,with " nanda yo " !!

Answer

"Busu wa kirai desu."
I hope you get this sentence at least.

".....kirai nandayo" is more strong, emotional, and rough(non-polite) version of  "....kirai desu."

Answer

That says "I hate an ugly woman !"
In fact,the correct and  sentence is "watashi ha busu ga kirai nanda."
watashi ha (omission)
ga→wa　(emphasis)
yo (emphasis,",you know")

Answer

...kirai na no desu yo.
That is the formal way of saying it. 
....na no desu you = na n da yo.
I hope that clears that up. I presume you have learned the "n desu" construction before.

Answer

"nan"or "nani" means "what"
"da" the simple form of "desu"
"yo" I think you can't translate it,it's used to confirm your feelings...etc.
I hope I helped you.
