    Perhaps you could try using the tikz-cd package. https://ctan.org/pkg/tikz-cd?lang=en Try it and let us know where you get stuck. – Benjamin McKay Aug 10 '19 at 06:49

    For star see https://tex.stackexchange.com/questions/490500/ (it is only similar). Also search for questions tagged as tikz-cd. Also reading of tikz-cd package will be helpful. – Zarko Aug 10 '19 at 07:15

    You can use general graph drawing as a starting point. https://tex.stackexchange.com/a/474634/116513 – qwr Aug 11 '19 at 00:49

We use the tikz-cd-package for this. If you are a beginner, you probably should have a look at this online-editor.

\documentclass[a4paper]{article}

\usepackage{tikz-cd}

\begin{document}

\begin{tikzcd}[row sep = huge, column sep = huge]
A \arrow[r, "\varphi_1"] \arrow[d, "\varphi_2", swap] \arrow[dd, bend right = 40, "\varphi_8", swap] & B \arrow[d, "\varphi_3"] \arrow[dd, bend left = 40, "\varphi_9"] \\
C \arrow[r, "\varphi_4"] \arrow[d, "\varphi_5", swap]                             & D \arrow[d, "\varphi_6"]                       \\
E \arrow[r, "\varphi_7", swap]                  & F                                
\end{tikzcd}
\end{document}
