Is there a way to automate setting nodes at the intervals of the foreach marks so they can be referred to, for drawing the braces; instead of defining their locations manually.

You can try something like this:

foreach[count=j] i in {a,b,...,f}

    draw[-|] (j,0) -- ++(1,0)node[below]{i}coordinate(i);

to draw lines and name the nodes using foreach.

MWE

documentclass[border=3mm]{standalone}

usepackage{pgfplots}

tikzset{brce/.style={blue, thick, decorate, decoration={brace,amplitude=.16cm},}}

tikzset{brcetxt/.style={blue!80!black, midway, xshift=0cm,}}

begin{document}

begin{tikzpicture}

foreach[count=j] i in {a,b,...,f}

    draw[-|] (j,0) -- ++(1,0)node[below]{i}coordinate(i);

draw (f)--++(1,0);



draw [brce,decoration=mirror] (b|-0,-.4) -- (d|-0,-.4) node [brcetxt,yshift=-.5cm] {middle};

draw [brce] (a|-0,.2) -- (b|-0,.2) node [brcetxt, yshift=.5cm] {series};

draw [brce] (e|-0,.2) -- (f|-0,.2) node [brcetxt, yshift=.5cm] {draw};

end{tikzpicture}
