blank page between section and figures

I am trying to create an Appendix for my experiment figures, and the following is the my code

section{}label{sec:figures}

begin{figure*}[h]
    begin{minipage}{0.75textwidth}  
        ...
    end{minipage}      
end{figure*}

begin{figure*}[h]
    begin{minipage}{0.75textwidth}  
        ...
    end{minipage}      
end{figure*}

begin{figure*}[h]
    begin{minipage}{0.75textwidth}  
        ...
    end{minipage}      
end{figure*}

begin{figure*}[h]
    begin{minipage}{0.75textwidth}  
        ...
    end{minipage}      
end{figure*}

There is unintentional blank page inserted between the section title and the figures like the following.

How can I make latex not do this unintentional page break?
Thanks.

Update:
I have tried using the float package with

begin{figure}[H]
    begin{minipage}{0.75textwidth}  
        ...
    end{minipage}      
end{figure}

The problem with this is that I am using a two-column format and this made the picture overlay on each other.
