How would you modify the following code so that the words "First shape", "Second shape", and "third shape" are vertically aligned?

Thank you!

matchstick

    Thank you for posting a working example! At the same time, much of your code does not seem to be relevant to the question you're asking here. Please limit the example to only the code required for your issue to appear. You can have a look at this guide for how to prune your code for this purpose. Commented 2 days ago

You could let the adjustbox package do the vertical alignment for you:

\documentclass{book}

\usepackage{tikz}
\usepackage{adjustbox}
\usepackage{amsmath}

\begin{document}

$\begin{array}[b]{lcc}
\text{First shape}
&
\quad
&
\begin{adjustbox}{valign=c}
\begin{tikzpicture}
%left
\node[rotate around={+60:(-0.2,-0.5)}] (image) at (-0.2,-0.5) {\includegraphics[]{Stick.png}};
\node[rotate around={+120:(-0.35,+0.15)}] (image) at (-0.35,+0.15) {\includegraphics[]{Stick.png}};
%center
\node[] (image) at (0,0) {\includegraphics[]{Stick.png}};
%right
\node[rotate around={-60:(0.2,-0.5)}] (image) at (0.2,-0.5) {\includegraphics[]{Stick.png}};
\node[rotate around={-120:(0.35,+0.15)}] (image) at (0.35,+0.15) {\includegraphics[]{Stick.png}};
\end{tikzpicture}%
\end{adjustbox}%
\\
\end{array}$

\end{document}

I would suggest using tabular. With tabular, all labels are placed in the first column and therefore appear strictly one under another, while baseline=(current bounding box.center) ensures that all three drawings are aligned vertically in the same way relative to the text.

Note that since I do not have the matchstick image, I added its drawing in the preamble and introduced the command \onehouse to simplify the code. You are free to do whatever you like with this code, including completely ignoring it.:)

\documentclass{article}
\usepackage{tikz}

% "Matchstick" defined as a pic
\tikzset{
  pics/stick/.style={
    code={
      % wooden stick
      \fill[brown] (-0.45,-0.05) rectangle (0.45,0.05);
      % match head
      \fill[red]   (-0.45,0) circle[radius=0.08];
    }
  }
}

% One "house" made of five matchsticks
\newcommand{\onehouse}{%
  \pic[rotate=60]   at (-0.2,-0.5)  {stick};
  \pic[rotate=120]  at (-0.35,0.15) {stick};
  \pic              at (0,0)        {stick};
  \pic[rotate=-60]  at (0.2,-0.5)   {stick};
  \pic[rotate=-120] at (0.35,0.15)  {stick};
}

\begin{document}

\begin{center}
\begin{tabular}{@{}l@{\qquad}l@{}}
First shape &
  \begin{tikzpicture}[baseline=(current bounding box.center)]
    \onehouse
  \end{tikzpicture}
\\[1ex]
Second shape &
  \begin{tikzpicture}[baseline=(current bounding box.center)]
    \onehouse
    \begin{scope}[xshift=1.6cm] % shift for the second house
      \onehouse
    \end{scope}
  \end{tikzpicture}
\\[1ex]
Third shape &
  \begin{tikzpicture}[baseline=(current bounding box.center)]
    \onehouse
    \begin{scope}[xshift=1.6cm] % second house
      \onehouse
    \end{scope}
    \begin{scope}[xshift=3.2cm] % third house
      \onehouse
    \end{scope}
  \end{tikzpicture}
\end{tabular}
\end{center}

\end{document}

    @Sebastiano To be honest, I am not entirely sure that I have fully and correctly understood the OP either. But let’s see what they say. Commented 2 days ago

I would have been quicker using bclogo, taking even the top part of the matchstick and camouflaging it.

\documentclass{article}
\usepackage{lipsum}    
\usepackage[tikz]{bclogo}
\usepackage[dvipsnames]{xcolor}
\newcommand{\bcimg}{\hspace{-.11cm}\includegraphics[width=\logowidth]{fia.png}}
\definecolor{fia}{RGB}{226, 193, 112}
\begin{document}

\begin{bclogo}[
    couleur=white,
    couleurTexte=black,
    couleurBarre=fia,
    couleurBord=white,
    epBarre=4.7, % <- --------- increase Barre
    logo=\bcimg
]{Mon Titre}
\lipsum[4]
\end{bclogo}

\end{document}
