How can I align the numbers, st, nd, rd and th? As you can see they aren't aligned.

I'm trying to recreate this:

(For some reason the image is flipped.)

Your font choice AlegreyaSans uses lining figures with variable widths by default. That means the glyph width of digits are not constant but varies according the shape of the digit glyph.

The package defines the font \AlegreyaSansLTF for lining figures in tables with constant width for better vertical alignments in tables.

The following example uses \textsuperscript for raising the suffix letters. Also, the example uses package array to smuggle in a macro at the start of the cell for formatting the ordinal number.

\documentclass[10pt]{article}

\usepackage{array}
\usepackage{ulem}

\newcommand{\unline}[1]{\rule[0pt]{#1}{0.6pt}}

\usepackage[T1]{fontenc}
\usepackage[sfdefault]{AlegreyaSans}

\begin{document}

\newcommand*{\myordnum}[5]{%
  #1% \ignorespaces, automatically added at the begin of a tabular cell
  \AlegreyaSansTLF
  #2#3%
  \textsuperscript{#4#5}%
}
\begin{tabular}{>{\myordnum}ll>{\myordnum}ll}
  {}1st & first        &  17th &  seventeenth   \\
  {}2nd & \unline{2cm} &  18th &  \unline{2cm}  \\
  {}3rd & \unline{2cm} &  19th &  \unline{2cm}  \\
  {}4th & \unline{2cm} &  20th &  \unline{2cm}  \\
  {}5th & \unline{2cm} &  21st &  \unline{2cm}  \\
  {}6th & \unline{2cm} &  22nd &  \unline{2cm}  \\
  {}7th & seventh      &  23rd &  \unline{2cm}  \\
  {}8th & \unline{2cm} &  24th &  twenty-fourth \\
  {}9th & \unline{2cm} &  25th &  twenty-fifth  \\
  10th  & \unline{2cm} &  26th &  twenty-sixth  \\
  11th  & \unline{2cm} &  27th &  \unline{2cm}  \\
  12th  & \unline{2cm} &  28th &  twenty-eighth \\
  13th  & \unline{2cm} &  29th &  \unline{2cm}  \\
  14th  & fourteenth   &  30th &  \unline{2cm}  \\
  15th  & \unline{2cm} &  31st &  \unline{2cm}  \\
  16th  & sixteenth    \\
\end{tabular}

\end{document}

Variant with right aligned digits:

\newcommand*{\myordnum}[5]{%
  #1% \ignorespaces, automatically added at the begin of a tabular cell
  \leavevmode
  \AlegreyaSansTLF
  \ifx\\#2\\% first digit is empty?
    \hphantom{0}%
  \fi
  #2#3%
  \textsuperscript{#4#5}%
}

[Tex/LaTex] Align Numbers in tabularx with standard deviation

To get table alignment using siunitx, do not put the numbers inside \num but just straight inside an S-type column. Here, I'd probably go for something like

\documentclass{article}
\usepackage{booktabs}
\usepackage{siunitx}
\begin{document}
\sisetup{separate-uncertainty}
\begin{tabular}
  {@{} 
    l
    >{\approx}S[table-format = \approx3]
    S[table-format = 2.2(2)]
    S[table-format = 1.2(2)]
  @{}}
  \toprule
    & \multicolumn{3}{c}{Dimensions/\si{mm}} \\
    &  \multicolumn{1}{c}{Length} & {Width} & {Thickness} \\
  \midrule
    Quasi-static \& fatigue & 200 & 24.90(20) & 1.95(7)  \\
    Short beam              &  20 &  4.99(5)  & 2.00(7)  \\
    Impact                  &  65 & 13.48(21) & 1.95(11) \\
  \bottomrule
\end{tabular}
\end{document}

(I've combined the units into one place as the repeats seems superfluous, but that's of course down to you.) Notice that I've put the \approx into the table header, so for the Length heading I need a \multicolumn to avoid a stray one!

[Tex/LaTex] Getting extra equation numbers using align environment

Just omit the line-break directive at the end of the final equation in a given align group. E.g.,

\begin{align}
    P(t) &= \tfrac{3}{2}[v_d(t)i_d(t)] \\
    Q(t) &= \tfrac{3}{2}[-v_d(t)i_q(t)] % <- no "\\" directive
\end{align}

As the code shows, I would also (a) remove the \left and \right qualifiers as they actually don't do anything for the cases at hand and (b) replace \frac with \tfrac.

If you have a multi-line equation that should be assigned just one equation number, don't use an align environment. Instead, use a split environment inside an equation environment.

By the way, the arrows produced by \overrightarrow look disproportionately large; consider using \vec instead. For arrows (and other diacritics) set above the characters i and j, it's traditional to omit the "dot", i.e., to use a "dotless" i and j; this may be achieved in math mode by writing \imath and \jmath. Separately, I again would not use \left and \right to autosize the round parentheses and curly braces; consider using \bigl and \bigr instead. (By the way, the outermost round parentheses may be omitted in all three rows, right?)

\documentclass{article}
\usepackage{amsmath}
\numberwithin{equation}{section}
\begin{document}

\setcounter{section}{1} % just for this example 
\setcounter{equation}{31}
\begin{align}
    P(t) &= \tfrac{3}{2}[v_d(t)i_d(t)] \\
    Q(t) &= \tfrac{3}{2}[-v_d(t)i_q(t)] 
\end{align}

\setcounter{equation}{20} % just for this example
\begin{equation}\begin{split}
P(t) 
&= \frac{
\Re\bigl\{\vec{v}(t)\vec{\imath}(t)\bigr\} + 
\Re\bigl\{\vec{v}(t)\vec{\imath}(t)^*\bigr\}}{2} \\
&\quad+ \frac{
\Re\bigl\{\vec{v}(t)\vec{\imath}(t)e^{-j\frac{4\pi}{3}}\bigr\} + 
\Re\bigl\{\vec{v}(t)\vec{\imath}(t)^*\bigr\}}{2} \\
&\quad+ \frac{
\Re\bigl\{\vec{v}(t)\vec{\imath}(t)e^{-j\frac{8\pi}{3}}\bigr\} + 
\Re\bigl\{\vec{v}(t)\vec{\imath}(t)^*\bigr\}}{2} 
\end{split}\end{equation}
\end{document}
