    sir in the graphs of electric field due to binary charge configuration
    why some curves are below x axis and some
    are above x axis

    Show one of your graphs; the axes of the graph depend upon the conventions chosen for the coordinate system.

    Those seem to be graphs of E along the line connecting the two charges. Remember E is actually a vector: it has magnitude and direction. At some points, E is to the right (shown as positive on the graph); at other points, E is to the left (shown as negative on the graph).
