It's not clear to me why '0' was used though '0' appears in forth naming
conventions meaning 'initialization'.

In the word names like `ndrop`, `n>r`, `nr>` I consider `n` as an
indicator of the data type on which these words operate.

I agree with as n counts, # is better.

Other examples.

In the words like `2swap`, `2>r`, `2drop`, `2!`, etc, `2` is an
indicator of the data type ( 2*x ), that is an unspecified pair ( x x ).

I don't like words that start with a digit. pswap p! p>r etc. is better.

But in the word `2/` (and non-standard `2+`), `2` is not a data type
indicator. Therefore, this name conflicts and is best avoided/eliminated.

 2/  is misleading because is is not the same as 2 / .
Because they are actually shift operators  >>A and <<A are better.
(Because actual normal shifts are << and >> ).

Agreed.

Now go design your own language. (I did).
