I am trying to draw arrows between the nodes in a graph as you can see in the picture below. The arcs are not nice as they don't coincide with the radius I want and that I drawn as a dotted line. Many thanks for any advice.

UPDATE: I forgot to mention that I want to write a text above each arc also. UPDATE 2: New code and result at the end of this post.

\documentclass[border=1cm]{standalone}
\usepackage{tikz}
\usetikzlibrary{arrows.meta, automata,
                calc,
                positioning,
                quotes}


\begin{document}
 \begin{tikzpicture}[auto, node distance = 30mm and 40mm,
        dot/.style = {circle, fill=red, inner sep=2pt, node contents={}},
every state/.style = {circle, draw=red, very thick},
 every edge/.style = {draw=blue, line width=1pt, -Stealth,
                      shorten >=2pt, shorten <=2pt,
                      },
 every edge quotes/.style = {auto, sloped, inner sep=2pt},
       every label/.style = {rectangle, inner sep=2pt, font=\large},
     mincut/.style = {draw=green!40!black, line width=3pt, dashed}
                                              ]

 \foreach [count=\i] \ang in {60} 
 { 
\node[state]         (1) at (120:5cm)         {$1$};

\node[state]         (2) at (\ang+120:5cm)    {$2$};

\node[state]         (3) at (2*\ang+120:5cm)   {$3$};

\node[state]         (6) at (3*\ang+120:5cm)   {$6$};

\node[state]         (5) at (4*\ang+120:5cm)   {$5$};

\node[state]         (4) at (5*\ang+120:5cm)   {$4$};
}
;


\path       (1) edge["text 1",bend right]    (2)
                edge["text 2",bend left]     (4)
                edge[near start]    (6)
            
            (2) edge["text 3", bend right]   (3)
            
            (3) edge[ near start]   (4)
            
            (4) edge["text 4", bend left]    (5)

            (5) edge["text 5", bend left]    (6)            

            (6) edge["text 6", bend left]   (3);

\draw[-latex,dashed] (5,0) arc[start angle=0, end angle=360,radius=5cm];



\end{tikzpicture}
\end{document}

Here is my updated code that I made with help of the answers below.

\documentclass[border=1cm]{standalone}
\usepackage{tikz}
\usetikzlibrary{arrows.meta, automata,
                calc,
                positioning,
                quotes}


\begin{document}
 \begin{tikzpicture}[auto, node distance = 30mm and 40mm,
        dot/.style = {circle, fill=red, inner sep=2pt, node contents={}},
every state/.style = {circle, draw=red, very thick},
 every edge/.style = {draw=blue, line width=1pt, -Stealth,
                      shorten >=2pt, shorten <=2pt,
                      },
 every edge quotes/.style = {auto, sloped, inner sep=2pt},
       every label/.style = {rectangle, inner sep=2pt, font=\large},
     mincut/.style = {draw=green!40!black, line width=3pt, dashed}
                                              ]

 \foreach [count=\i] \ang in {60} 
 { 
\node[state]         (5) at (0:5cm)   {$5$};
\node[state]         (4) at (60:5cm)   {$4$};
\node[state]         (1) at (120:5cm)   {$1$};
\node[state]         (2) at (180:5cm)    {$2$};
\node[state]         (3) at (240:5cm)   {$3$};
\node[state]         (6) at (300:5cm)   {$6$};
}
;


\path       (1) edge["text 7",near start]    (6)
            
            (3) edge["text 8", near start]   (4);

% 1-4            
\draw[{Stealth}-,line width=1pt, blue] (60*1+5:5cm) arc (60*1+5:60*1+55:5cm) node [pos=0.5, above, red, sloped] {text 2};

% 4-5
\draw[{Stealth}-,line width=1pt, blue] (60*6+5:5cm) arc (60*6+5:60*6+55:5cm) node [pos=0.5, above, red, sloped] {text 4};

% 5-6
\draw[{Stealth}-,line width=1pt, blue] (60*5+5:5cm) arc (60*5+5:60*5+55:5cm) node [pos=0.5, above, red, sloped] {text 5};

% 6-3
\draw[{Stealth}-,line width=1pt, blue] (60*4+5:5cm) arc (60*4+5:60*4+55:5cm) node [pos=0.5, above, red, sloped] {text 5};

% 1-2            
\draw[-{Stealth},line width=1pt, blue] (60*2+5:5cm) arc (60*2+5:60*2+55:5cm) node [pos=0.5, above, red, sloped] {text 1};

% 2-3
\draw[-{Stealth},line width=1pt, blue] (60*3+5:5cm) arc (60*3+5:60*3+55:5cm) node [pos=0.5, above, red, sloped] {text 3};


\end{tikzpicture}
\end{document}

which results in this graph.

You could use arc to draw the perfect curves between nodes, but you should provide some offset to not overlap with the nodes.

\documentclass[border=1cm]{standalone}
\usepackage{tikz}
\usetikzlibrary{arrows.meta, automata, calc, positioning, quotes}

\begin{document}

\begin{tikzpicture}[auto, node distance = 30mm and 40mm,
        dot/.style = {circle, fill=red, inner sep=2pt, node contents={}},
every state/.style = {circle, draw=red, very thick},
 every edge/.style = {draw=blue, line width=1pt, -Stealth, shorten >=2pt, shorten <=2pt,},
 every edge quotes/.style = {auto, sloped, inner sep=2pt},
       every label/.style = {rectangle, inner sep=2pt, font=\large},
     mincut/.style = {draw=green!40!black, line width=3pt, dashed}
                                              ]
\foreach [count=\i] \ang in {60} { 
 \node[state]         (1) at (120:5cm)        {$1$};
 \node[state]         (2) at (\ang+120:5cm)   {$2$};
 \node[state]         (3) at (2*\ang+120:5cm) {$3$};
 \node[state]         (6) at (3*\ang+120:5cm) {$6$};
 \node[state]         (5) at (4*\ang+120:5cm) {$5$};
 \node[state]         (4) at (5*\ang+120:5cm) {$4$};
};

\foreach \i in {0,...,5}
 \draw[{Stealth}-,line width=1pt] (60*\i+5:5cm) arc (60*\i+5:60*\i+55:5cm);

\end{tikzpicture}

\end{document}

No guru solution:

\documentclass[border=1cm]{standalone}
\usepackage{tikz}

\begin{document}

\begin{tikzpicture}

    \foreach \i in {1,...,6}{%
        \draw[-latex,line width=2pt] (60*\i+5:5cm) arc (60*\i+5:60*\i+55:5cm);
        \draw[red] (60*\i:5cm) circle(12pt);
        \node at (60*\i:5cm) () {$\i$};
        }
    \filldraw (0,0) circle(2pt); % comment this line if you dont want the circle center 

\end{tikzpicture}

\end{document}

Output:

EDIT: For your's edited request:

\documentclass[border=1cm]{standalone}
\usepackage{tikz}

\begin{document}

\begin{tikzpicture}
    \foreach \i in {1,...,6}{%
        \draw[blue,-latex,line width=2pt] (60*\i+5:5cm) arc (60*\i+5:60*\i+55:5cm) node [pos=0.5, above, red, sloped] {text\i};
        \filldraw[red!20] (60*\i:5cm) circle(12pt);
        \node at (60*\i:5cm) (\i) {$\i$};
        }
    \draw[blue,-latex,shorten >=5pt, shorten <=5pt] (2)--(5) node [pos=0.3, above, red, sloped] {text7};;
    \draw[blue,-latex,shorten >=5pt, shorten <=5pt,] (4)--(1) node [pos=0.3, above, red, sloped] {text8};;
    \filldraw (0,0) circle(2pt);
\end{tikzpicture}

\end{document}
