Answer 1

You could use minipages:

\documentclass[10pt,a4paper]{article}
\usepackage{float}
\usepackage[a4paper,margin=0in,footskip=0in]{geometry}
\usepackage[export]{adjustbox}
\usepackage{graphicx}

\begin{document}
\begin{figure}[htbp]
\begin{minipage}[t]{.45\textwidth}%
\includegraphics[width=\textwidth,valign=T]{example-image-9x16}
\end{minipage}%
\hfill%
\begin{minipage}[t]{.45\textwidth}
\includegraphics[width=\textwidth,valign=T]{example-image-duck}%

\medskip
\includegraphics[width=\textwidth,valign=T]{example-image-duck}%
\end{minipage}%
\end{figure}

\end{document}
