I'm Japanese.

nandaka and nanka are the same meanings as your understanding

but nante nad nanka are different.

[それ何てじゃない！！ そういうつもりなんかない！]

それ何てじゃない is a little ??? Japanese for us. それ何かじゃない sounds right.

So you should learn a little bit of 何て.

*

何だか恥ずかしい mean;

I'm ashamed even I don't know why so.

LittleMoe, you are fairly good with Japanese language!

>To me, nanka means "kinda" as in "i was kinda embarrassed.

And nandaka appears to mean the same.<

Yes, you are right indeed.

>I know that nanka can also be a shortening of nanika<

OK.

>& be used similarly to nante as in それ何てじゃない！<

No! This is somewhat funny.

I'm not sure what you mean by それ何てじゃない！

But I think you should say:

それなんかじゃない！That isn't what I want!

or

それどころじゃない！This is no time to do that!

そういうつもりなんかない！

This is OK.
