When there are many nodes each have different names like n1, n2, n3, c1, c2 ,c3 ... after a while I started to get lost which node has which name.

Hence, we can help grid help lines using \draw[help lines] (0,0) grid (8,5);.

Can we apply similiar approach for defined node names? like if a node's name is n1, can n1 show up next to node in slightly gray color and apply this for all the nodes in the tikzpicture?

This combines Andrew Stacey's answer to Every non-label node in TikZ.

You can also use my answer but Andrew's is safe for when PGF/TikZ updates.

Code

\documentclass[tikz]{standalone}
\tikzset{
  clear label/.style={prefix after command={[every non label/.style={}]}},
  every node/.style={every non label,clear label},
  every non label/.style={label={[font=\tiny,gray]:\tikzlastnode}}}
\begin{document}
\begin{tikzpicture}[]
\foreach \x in {A, ..., F}{
  \node[circle, draw] at (5*rand, 5*rand) {\x};
}

\node (abc) at (0,0) {x};
\end{tikzpicture}


\end{document}
