I have a five pics presented on one page. I find that the pics are so small I want to magnify them. But when I use larger linewidth in the includegraphics, pics are overlapped together. I think the best way is to move the (a)(c) a little bit left and the (b)(d) a little bit right. Then I have the space to zoom them. Is there any method? Thanks for your helping.

I suggest you make the following changes:

• Change all five instances of begin{subfigure}{0.4linewidth} to begin{subfigure}{0.475linewidth}. This will make the graphs wider.




• Change all five instances of [width=1.2linewidth] to [width=1linewidth]. This will get rid of the overlaps within each row.




• Replace both instances of qquad with hfill.




• Optional: Delete (or comment out) all instances of centering except the very first one.




• Optional: Provide for a bit of vertical whitespace between the rows, by inserting medskiip (or bigskip) instructions.

Additionally to Mico's suggestion you can indeed use (parts of) the page margins, if you need. KOMA-Script provides an environment addmargin to increase or decrease the current margins of an area. If you do not use a KOMA-Script class you can use package scrextend as shown here:

documentclass{article}

usepackage{subcaption,graphicx,scrextend}



usepackage{showframe}% only to illustrate the page areas



begin{document}

begin{figure}

  begin{addmargin}{-dimexprmarginparwidth+marginparseprelax}

    centering

    begin{subfigure}{0.475linewidth}

      includegraphics[page=1,width=1.0linewidth]{example-image-duck}

      caption{}

      label{fig:hard_cokntact}

    end{subfigure}%

    hfill

    begin{subfigure}{0.475linewidth}

      includegraphics[page=2,width=1.0linewidth]{example-image-duck}

      caption{}

      label{fig:penaltyh method}

    end{subfigure}



    medskip

    begin{subfigure}{0.475linewidth}

      includegraphics[page=3,width=1.0linewidth]{example-image-duck}

      caption{}

      label{fig:hard_cokntact}

    end{subfigure}

    hfill

    begin{subfigure}{0.475linewidth}

      includegraphics[page=4,width=1.0linewidth]{example-image-duck}

      caption{}

      label{fig:penaltyh method}

    end{subfigure}



    medskip

    begin{subfigure}{0.475linewidth}

      includegraphics[page=5,width=1.0linewidth]{example-image-duck}

      caption{}

      label{fig:hard_cokntact}

    end{subfigure}

  end{addmargin}

There are other packages, that provide similar environments.
