I have the following definition.
far int* near IntegerPointer;
Does this mean, a pointer placed in 'near' memory pointing to a integer placed in far memory area.
Can anyone please clarify.

[psyhic power on] Yes you are right. :) [psyhic power off]
Just simple
@far int* IntegerPointer;
would be just pointer to far memory, whereas
int* @near IntegerPointer;
looks like pointer placed in near memory.

Yes, you got that right.
Read declarations (from the inside out and) from right to left:
@far int* @near IntegerPointer;
^^^^^^^^^^^^^^
IntegerPointer is a
@far int* @near IntegerPointer;
^^^^^
IntegerPointer is a @near
@far int* @near IntegerPointer;
^
IntegerPointer is a @near pointer
@far int* @near IntegerPointer;
^^^
IntegerPointer is a @near pointer to int
@far int* @near IntegerPointer;
^^^^
IntegerPointer is a @near pointer to int @far
or IntegerPointer is a @near pointer to @far int
What @near and @far means, though, I have almost no idea.

Different addressing methods, I think.

Windows C compilers used to have near and far pointers, being (IIRC) 16 and 32 bits respectively. I don't know why the "@" either, since it isn't in the body of the question.
