Okay, sorry for the trouble but I think I found a solution. So I am going to just post it here so that anyone else using this particular CV class can use it as well.
The problem that I mentioned in my question, I figured, persists because when we type the command \makeprofile
again to print the side bar in the second page it prints everything that is in its original textblock.
In order to extend the side bar to the second page, I would create another new command called \makenewprofile
and within this command I would create a text block with those sections that I would like to appear as an extension of the side bar in my second page
\newcommand{\makenewprofile}{
\begin{tikzpicture}[remember picture,overlay]
\node [rectangle, fill=sidecolor, anchor=north, minimum width=9cm, minimum height=\paperheight+1cm] (box) at (-5cm,0.5cm){};
\end{tikzpicture}
\begin{textblock}{6}(0.5,0.2)
\profilesection{Languages}
\skillslang
\langtext
\scriptsize
(*)[The skill scale is from 1 (Anf{\"a}nger) to 6 (Muttersprachige)]
\end{textblock}
}
In this way whatever sections I include within the new textblock within the command \makenewprofile
will then appear in the second page when called in the main tex file which gives me the output as shown in the picture which is precisely what I wanted 
In order to use my example, you have to modify the class file twentysecondcv.cls
the section which has the following code needs to be modified
\newcommand{\makeprofile}{
\begin{tikzpicture}[remember picture,overlay]
\node [rectangle, fill=sidecolor, anchor=north, minimum width=9cm, minimum height=\paperheight+1cm] (box) at (-5cm,0.5cm){};
\end{tikzpicture}

\node[anchor=north west, inner sep=0pt, outer sep=0pt] at (0,0) {\includegraphics[width=\imagewidth]{\profilepic}};
\end{tikzpicture}
\end{center}

If you want to use the command \skillslang
as I use in my example, you have to define it just like skills is defined in the original twentysecondcv.cls
file. Using the exact same syntax as in the original, add it onder the original "command for printing skill progress bars" (this also works for adding various other types of skills, just define another one just like this).
% Command for printing skill progress bars
\newcommand\skillslang[1]{
\renewcommand{\skillslang}{
\begin{tikzpicture}
\foreach [count=\i] \x/\y in {#1}{
\draw[fill=maingray,maingray] (0,\i) rectangle (6,\i+0.4);
\draw[fill=white,mainblue](0,\i) rectangle (\y,\i+0.4);
\node [above right] at (0,\i+0.4) {\x};
}
\end{tikzpicture}
}
}
