How can we write the below image (an 'm') and n_E in TeX format?

    Welcome to TeX.SX! Could you give us some smaller illustration example? :-) Please provide a minimal document and tell us, if you use pdfLaTeX or others. And edit your title to something that will help other users in future. Like this, people will be happy to help you. Thanks. – LaRiFaRi Sep 05 '14 at 11:41

Your "M"-symbol looks like a fracture letter. The most typical way is to use the command \mathfrak{} from the package amsfonts. You have to use this in math-mode.

% arara: pdflatex

\documentclass{article}
\usepackage{amssymb} % which loads amsfonts

\begin{document}
$\mathfrak{M}_E$
\end{document}

enter image description here

The unicode for this symbol is U+1D510. When using Lua- or XeLaTeX, you could load it e.g. with \symbol{"1D510} from fontspec or \mfrakM from unicode-math.

% arara: lualatex

\documentclass{article}
\usepackage{unicode-math}
\usepackage{booktabs}

\begin{document}
\begin{tabular}{l c }
    \toprule
    Font & Example\\
    \midrule
    Latin Modern & $\mfrakM_E$\\
    Asana & \setmathfont{Asana Math}$\mfrakM_E$\\
    XITS & \setmathfont{XITS Math}$\mfrakM_E$\\
    TeX Gyre Pagella & \setmathfont{Tex Gyre Pagella Math}$\mfrakM_E$\\
    \bottomrule
\end{tabular}
\end{document}

Update:

Regarding your second question. You can make this image as follows:

% arara: pdflatex: {shell: yes}

\documentclass[convert]{standalone}
\usepackage{amsfonts}    
\begin{document}
    $\scriptscriptstyle\mathfrak{N}_E$
\end{document}
