Horizontally aligning text a certain distance from the margin

Question

I am making examination questions, and would like to align the question numbers across the question paper.

This is my effort so far:

\documentclass{article}
\usepackage[a4paper, portrait, margin=0.5in]{geometry}
\usepackage{fontspec}
\usepackage{anyfontsize}
\renewcommand{\familydefault}{\sfdefault}
\newcommand{\RNum}[1]{\uppercase\expandafter{\romannumeral #1\relax}}
\setsansfont{Times New Roman} \fontsize{11.5pt}{13.8pt}\selectfont

\begin{document}
\thispagestyle{empty}
\noindent \textbf{Formatting for Questions} \\
\\
\textbf{1} \hspace{0.5495cm} \textbf{(a)} \hspace{0.2cm} Question here \\
\hspace*{0.8525cm} \textbf{(a)} \hspace{0.1525cm} Question here \\
\hspace*{1.6775cm} Question here \\
\hspace*{0.8525cm} \textbf{(a)} \hspace{0.14cm} \textbf{(i)} \hspace{0.1485cm} Question here \\
\hspace*{0.8525cm} \textbf{(b)} \hspace{0.1175cm} \textbf{(i)} \hspace{0.1485cm} Question here \\
\hspace*{0.8525cm} \textbf{(d)} \hspace{0.1175cm} \textbf{(i)} \hspace{0.1485cm} Question here \\
\hspace*{1.6645cm} \textbf{(i)} \hspace{0.15cm} Question here \\
\hspace*{1.55175cm} \textbf{(ii)} \hspace{0.15cm} Question here \\
\hspace*{1.43925cm} \textbf{(iii)} \hspace{0.1515cm} Question here \\
\hspace*{2.4cm} Question here \\
\hspace*{0.8525cm} \textbf{(b)} \hspace{0.1285cm} Question here \\
\hspace*{0.8525cm} \textbf{(c)} \hspace{0.17375cm} Question here \\
\hspace*{0.8525cm} \textbf{(d)} \hspace{0.12825cm} Question here \\
\hspace*{0.8525cm} \textbf{(e)} \hspace{0.1735cm} Question here \\
\hspace*{0.865cm} Question here
\end{document}

As seen above, I have been using \hspace to align the question numbers, but it is rather inefficient and slightly inaccurate given the endless combinations of sub-questions.

My goal is for the following:

1. (a), (b), (d), etc. to start at the red line (not end together)
2. Second column Question here, (i) to start at the blue line (ignoring (ii) and (iii))
3. (i), (ii), (iii), etc. to end at the green line (not start together)
4. Fourth column Question here to start at the yellow line

Any help would be appreciated. Thanks in advance!

The enumitem package allows questions to be aligned natively. With the shortlabels

option, you can simply modify the labels by adding the desired type of label.

\documentclass{article}
\usepackage[a4paper, portrait, margin=0.5in]{geometry}
%\usepackage{fontspec}
\usepackage[shortlabels]{enumitem}
\usepackage{anyfontsize}
\renewcommand{\familydefault}{\sfdefault}
\newcommand{\RNum}[1]{\uppercase\expandafter{\romannumeral #1\relax}}
%\setsansfont{Times New Roman} \fontsize{11.5pt}{13.8pt}\selectfont

\begin{document}
\thispagestyle{empty}
\noindent \textbf{Formatting for Questions} \\
\\

\begin{enumerate}[1,leftmargin=10mm]
\item  Question here 
\item Question here 
\item \begin{enumerate}[(a),leftmargin=18pt]
        \item  Question here 
        \item Question here 
        \item  Question here 
            \begin{enumerate}[(i),leftmargin=16pt]
            \item  Question here 
            \item Question here 
            \item  Question here 
            \item Question here 
            \end{enumerate}
        \item Question here 
        \end{enumerate}
\item  Question here 
\item Question here 
\end{enumerate}

\end{document}
