Get at FILE_STANDARD_INFORMATION for the FO. If NumberOfLinks > 1, it’s
a hard linked file.

But that is per file info right. Is it not going to give NumberOfLinks > 1
for all FO of that file?.
But I want to know whether the particular FO is against hardlink or not.

Yes.

There is no such thing like a “hard link” and a “hard link target” (like
for shell shortcuts or reparse points). It’s just that there are
multiple directory entries pointing to the same file. You can refer to
FILE_INTERNAL_INFORMATION to find the hard linked file by IndexNumber.
Hard linked files share the same IndexNumber.
