| Will the size of the memory allocated within various(code,data,stack &
heap) segments for a process, be always multiple of 'page' size?

Yes; a page is the smallest unit of memory managed by the kernel. (A bit
of a simplification, I know.)
Well, let me expand on that a bit: the segment size will be a multiple
of the page size, but those segments may contain multiple lumps that
are not any integer multiple of the page size.

That's a meaingless question. It all depends upon what your definition
of "allocated" is.
