If you absolutely require a solution involving the multicol environment then the following addition from the subcaption package would work

\usepackage{multicol}
\usepackage{graphicx}
\usepackage{subcaption}

\begin{document}

    \begin{figure*}
        \centering
        \begin{multicols}{2}
            \subcaptionbox{Caption\label{fig:1}}{\includegraphics[width=\linewidth]{example-image-a}}\par 
            \subcaptionbox{Caption\label{fig:2}}{\includegraphics[width=\linewidth]{example-image-b}}\par 
        \end{multicols}
        \begin{multicols}{2}
            \subcaptionbox{Caption\label{fig:3}}{\includegraphics[width=\linewidth]{example-image-c}}\par
            \subcaptionbox{Caption\label{fig:4}}{\includegraphics[width=\linewidth]{example-image-A}}\par
        \end{multicols}
    \caption{Caption here}
    \end{figure*}

\end{document}

Note that there are many possible other solutions ; some of which use subfigure, minipage and other.
