I want to create a page in overleaf contains 4 sub-sub-figures, each figure has a sub-sub-caption ?
each two sub-sub-figures have its own sub-caption, as illustrated in the bellow picture:
Create a picture composed of 4 sub-sub-figures with 4 sub-sub-captions and 2 sub-captions

You can set the length \belowcaptionskip (default value 0pt) as you need it. Either do this locally inside the concerned figure environment as shown below or globally in the preamble.
\documentclass[11pt,a4paper,english]{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{babel}
\usepackage[font=small,labelfont=bf,tableposition=top]{caption}
\usepackage[font=footnotesize]{subcaption}
\begin{document}
\begin{figure}[!ht]
\setlength{\belowcaptionskip}{5pt}
\centering
\begin{subfigure}[b]{0.75\textwidth}
\rule{\linewidth}{0.5\linewidth}
\caption{First sub-figure}\label{fig:first}
\end{subfigure}
\begin{subfigure}[b]{0.75\textwidth}
\rule{\linewidth}{0.5\linewidth}
\caption{Second sub-figure}\label{fig:second}
\end{subfigure}
\caption{Two dummy sub-figures}\label{dummy}
\end{figure}
\end{document}
The caption manual has the details.
The following should be right up your allow. It's achieved with the aid of subcaption and some manual float management:
\documentclass{article}
\usepackage{verbatimbox}
\usepackage[T1]{fontenc}
\usepackage{fancyvrb,listings,caption}
\usepackage[labelformat=simple]{subcaption}
\usepackage[scaled=.73]{beramono}
\fvset{baselinestretch=0.94}
\parindent=0pt
\parskip = 6pt

\AtBeginDocument{\DeclareCaptionSubType{lstlisting}
\renewcommand{\p@sublstlisting}{\thelstlisting}
\renewcommand{\thesublstlisting}{(\alph{sublstlisting})}

Each of the listings are set in a box \verbsavebox of width .3333\linewidth (by setting xrightmargin=.6667\linewidth). These boxes, once set, are added using \subcaptionbox{<caption>}{\usebox{\verbsavebox}}, where <caption> includes both the caption and the \label.
Immediately inside the figure environment, we strategically update the \@captype to be lstlisting. This fools TeX to think that it's dealing with a float called lstlisting when you call \caption. This is necessary since the \subcaptions are set before the main \caption, which requires \p@lstlisting (the parent counter associated with the subcounter sublstlisting) to be set correctly. This is all related to the functionality of the subcaption package.
The subcaptions are defined \AtBeginDocument, which is to coincide with the float definitions of listings, which is done at the same time. subcaption requires a float to exist before it allows one to define subcaptions for it.

There are a lot of ways to achieve this. This is a example using
