My question is very similar to this, However, I would like to only change the name of Caption for a specific figure, instead of all figures. Is it even possible and if so, then how?

First, you have to redefine \figurename.
Option1: Without using the babel package:
\renewcommand{\figurename}{Fig.}
Option2: With babel (and English as language):
\addto\captionsenglish{\renewcommand{\figurename}{Fig.}}
For other babel languages you need to use the proper \captions<language> command instead of \captionsenglish in the command above.
For changing the separator between label and caption text, I recommend the caption package.
\documentclass{article}
\renewcommand{\figurename}{Fig.}
\usepackage[labelsep=endash]{caption}
\begin{document}
\begin{figure}
\centering
\rule{1cm}{1cm}
\caption{This is a figure}
\end{figure}
\end{document}
EDIT: In case anyone wonders how to change the caption name of tables: Redefine \tablename.
Add the redefinition to \extrasngerman:
\documentclass{article}
\usepackage[ngerman]{babel}
\usepackage{hyperref}
\addto\captionsngerman{\renewcommand{\figurename}{Abb.}}
\addto\extrasngerman{\renewcommand\figureautorefname{Abb.}}
\begin{document}
\autoref{fig:test}
\begin{figure}
\caption{test caption}
\label{fig:test}
\end{figure}
\end{document}

IFF your document is really similar to the linked question, then you could do this:
However, depending on what your real document looks like --- which is why an MWE is almost always advisable --- you may need to do something rather different.
