The solution I want
After compiling the above document, the \rhead and \chead are similar in position of height. I want the \rhead to be up and \chead to be down/after \rhead.
I have reviewed a post that included something like \header[C], but that did not work. I am using Miktex + texMaker. But do provide an example if you know how to do it with \header[C] :)

You could just wrap the central header in a minipage:
\documentclass[12pt,a4paper]{article}
\usepackage{enumitem}
\usepackage{fancyhdr}
\usepackage[margin=3cm]{geometry}
\usepackage{pgfplots}
\newlength{\tabcont}
\setlength{\parindent}{0.0in}
\setlength{\parskip}{0.05in}

\newcommand{\semester}{lipsum}
\newcommand{\TDAG}{lipsum}
\newcommand{\campus}{lipsum}
\newcommand{\dept}{lipsum}
\pagestyle{fancyplain}
\headheight 56.2pt
\chead{\begin{minipage}[t]{.3\textwidth}
\centering
\campus \\ \dept \\ \course \\ \coursen
\end{minipage}}
\lhead{\TDAG}
