I would like to do this (1) in big size using latex (a one surrounded by a circle)

is it possible without including the picture ?

With pstricks and pst-node, you can circle about whatever you want with the circlenode command. Note that you have to give a name (first argument of the command) even if you don't want to use it. It can be compiled withpdflatexif you load pstricks xith the pdf option and compile with the--shell-escape(TeX Live) or--enable-write18` (MiKTeX) switch :
\documentclass[12pt, a4paper]{article}
\usepackage[utf8]{inputenc}
\usepackage{lmodern}
\usepackage[T1]{fontenc}
\usepackage[pdf, x11names]{pstricks}%pdf,
\usepackage{pst-node}
\begin{document}
Blahblahblah… \raisebox{-0.4\height}{ \circlenode[linewidth=2.5pt, linecolor = PaleVioletRed3]%
{A}{\color{PaleVioletRed3}\Huge\bfseries \sffamily 12a}}
Blahblahblah
\end{document}
