I'm using XeLaTeX with fancyhdr. I need to have the footer wider than \textwidth. This is an intentional effect. The problem is that the footer is several lines long, so I want them to appear as a single paragraph, wider than \textwidth. I'm not sure how best to do that.

The first page of a chapter is typeset using the plain pagestyle so that it stands out from other pages. You can modify it with something like:
\fancypagestyle{plain}{%
\fancyfoot[LE, RO]{Apurba Paul}
\fancyfoot[LO, RE]{Using fancyhdr}}
to change the style so your footer is also on the first page of a chapter, leaving the default header unchanged.
You can use a \makebox for each row of subfigures (change the lengths to suit your needs):
\documentclass{article}
\usepackage[demo]{graphicx}
\usepackage{subcaption}
\usepackage{lipsum}
\begin{document}
\lipsum[2]
\begin{figure}
\makebox[\linewidth][c]{%
\begin{subfigure}[b]{.6\textwidth}
\centering
\includegraphics[width=.95\textwidth]{image1}
\caption{a test subfigure}
\end{subfigure}%
\begin{subfigure}[b]{.6\textwidth}
\centering
\includegraphics[width=.95\textwidth]{image2}
\caption{a test subfigure}
\end{subfigure}%
}\\
\makebox[\linewidth][c]{%
\begin{subfigure}[b]{.6\textwidth}
\centering
\includegraphics[width=.95\textwidth]{image3}
\caption{a test subfigure}
\end{subfigure}%
\begin{subfigure}[b]{.6\textwidth}
\centering
\includegraphics[width=.95\textwidth]{image4}
\caption{a test subfigure}
\end{subfigure}%
}
\caption{A figure with four subfigures}
\end{figure}
\end{document}
The demo option for graphicx simply replaces actual figures with black rectangles; do not use that option in your actual document.

Here's a simple way:
It doesn't look great, and you'll probably have to increase how much space the footer is allowed to take up, but you get the picture...
