Como posiciono esses três para que fiquem todos horizontalmente próximos um do outro?

Answer 1

Uma possibilidade é utilizar alignedambientes em tabela. Nas equações são \textnormal{exp}utilizados textnormal{max}operadores matemáticos \expe \maxrespectivamente. Para uma expressão semelhante, a notação -4.823 \times 10^{-4}é bastante usada :siunitx\num{-5.684e-4}

Com essas mudanças o código fica muito mais curto e claro:

\documentclass[a4paper, 11pt]{article}
\usepackage[margin=0.5in]{geometry}

\usepackage{nccmath}
    \counterwithin{equation}{section}
\usepackage{tabularray}
\UseTblrLibrary{siunitx}

\usepackage{hyperref}
    \urlstyle{same}

\begin{document}
\[
\begin{tblr}{colspec = {@{} X[1.2,c] X[0.9,c] X[0.9,c] @{}} }
    \begin{aligned}
\Delta m_{\exp} & = \mfrac{m_{\exp,\max} - m_{\exp,\min}}{2}    \\
\Delta m_{\exp} & = \mfrac{(\num{-5.684e-4}) - (\num{-4.823e-4})}{2}    \\
\Delta m_{\exp} &=-4.305\times10^{-5}
    \end{aligned}           
    &    \begin{aligned}
    \Delta y_{\exp} & = \mfrac{y_{\exp,\max} - y_{\exp,\min}}{2}    \\
    \Delta m_{\exp} & = \mfrac{1.003 - 0.9800}{2}   \\
    \Delta m_{\exp} & = 0.0115
        \end{aligned}
        &    \begin{aligned}
        \Delta x_{\exp} & = \mfrac{x_{\exp,\min} - y_{\exp,\max}}{2}    \\
        \Delta m_{\exp} & = \mfrac{2031.9\ldots - 1764.6\ldots}{2}      \\
        \Delta x_{\exp} & = 133.6
            \end{aligned}
    \end{tblr}
\]
\end{document} 

Answer 2

Use o \flalign*meio ambiente.

Answer 3

É isso que você quer? Fiz com que as três equações se ajustassem à largura do texto usando frações de tamanho médio quando necessário. Aliás, você não precisa carregar colortbl se carregar xcolorcom option table, pois o último faz isso por você.
