Answer 1

使用capt-of包：

\documentclass[demo]{beamer} % in real document remove option "demo"
\setbeamertemplate{caption}[numbered]
\setlength\abovecaptionskip{0ex}
\setlength\belowcaptionskip{1.5ex}
\usepackage{capt-of}

\begin{document}
\begin{frame}{Einführung 2}
    \begin{columns}
    \column{0.5\textwidth}
        \centering
        \includegraphics[height=2.5cm]{FiguresAndPictures/AlleAktien-Netflix-Logo.png}
        \captionof{figure}{A}

        \includegraphics[height=4cm]{FiguresAndPictures/Amazon-Logo.jpg}
        \captionof{figure}{B}
    \column{0.5\textwidth}
        \centering
        \includegraphics[height=4cm]{FiguresAndPictures/facebook.png}
        \captionof{figure}{C}
    \end{columns}
\end{frame}
\end{document}
