Assume I have a 16 bit or 4 hex characters field and data in it is in little endian
This is little endian
B8 00 00 00
I want big endian of above
Should it be
00 00 00 B8
or
what?
or If I have char 1 byte "0x1D" should it be same?
or if I have array[2]={0xiD,2E} what would be big endian data should it be of the following.

If this is the binary representation of a 32 bit integer, then yes.
If I have char 1 byte "0x1D" should it be same?
Endianess only applies to words (2, 4, 8 bytes data types), not to bytes. That is, integer or floating point types.
if I have array[2]={0xiD,2E} what would be big endian data
That doesn't make sense unless this is the binary representation of a larger type. Endianess doesn't apply to raw data (or strings).
