Siempre que la sangría de los títulos de las secciones no sea un problema, lo siguiente podría ser un punto de partida:
\documentclass[a4paper]{article}
\usepackage{hyperref}
\setcounter{tocdepth}{5}
\setcounter{secnumdepth}{5}
\renewcommand\thesection{\Roman{section}.}
\renewcommand\thesubsection{\arabic{subsection}.}
\renewcommand\thesubsubsection{(\arabic{subsubsection})}
\renewcommand\theparagraph{\arabic{paragraph})}
\renewcommand\thesubparagraph{\arabic{subparagraph})}
\AtBeginDocument{%
\csname @ifpackageloaded\endcsname{hyperref}{%
% \theH... -macros are used ny hyperref's automatic creating of
% anchor-names/destination-names for hyperlinking. Anchor-names/
% destination-names must be unique within the document.
\renewcommand\theHsection{\thesection}%
\renewcommand\theHsubsection{\theHsection\thesubsection}%
\renewcommand\theHsubsubsection{\theHsubsection\thesubsubsection}%
\renewcommand\theHparagraph{\theHsubsubsection\theparagraph}%
\renewcommand\theHsubparagraph{\theHparagraph\thesubparagraph}%
}{}%
}%
\begin{document}
\tableofcontents
\section{First Section}
\subsection{First Subsection}
\subsubsection{First Subsubsection}
\paragraph{Paragraph (maybe?)}
\paragraph{Paragraph}
\paragraph{paragraph}
\subsection{Second Subsection}
\section{Second Section}
\end{document}

Por supuesto, puedes usarpárrafohacer unsubsubsubsección, el código es el siguiente:
\usepackage{titlesec}
\setcounter{secnumdepth}{4} % how many sectioning levels to assign numbers to
\setcounter{tocdepth}{4} % how many sectioning levels to show in ToC
\titleformat{\paragraph}
{\normalfont\normalsize\bfseries}{\theparagraph}{1em}{}
\titlespacing*{\paragraph}
{0pt}{3.25ex plus 1ex minus .2ex}{1.5ex plus .2ex}
\newcommand{\subsubsubsection}{\paragraph} %define newcommand \subsubsubsection
