Hi Nitin,
IF both files are on the exact same grid and the second file has data
over India and missing data elsewhere, you can use the where function
like this:
; file 1 = arr, file 2 = india with missing data denoted by india@_FillValue
data_combine = data ; allocate metadata + data (data will be
overwritten @next line though)
data_combine = where(ismissing(india), arr, india) ; where the india
array is missing, use the arr data, otherwise use the india data

As always check the results to make sure the results are as expected.
If that does not help or does not apply to your situation please respond
to the ncl-talk email list only.
