How to remove label and number from cref?

Question

I am trying to reference multiple subfigures in the caption of a figure separated by dash.
For example, the caption of the figure should look like:

Fig1. this is a figure. (a) first figure. (b) second figure. (c-e) the
rest of figures.

When I try using labelcref the figure number still appears:

Fig1. this is a figure. (a) first figure. (b) second figure. 1(c) to 1(e) the
rest of figures.

how can I remove the number and label and just keep the letters?
The solution here did not work for me because of multiple unrecogniazed command errors, and it is too complicated.
documentclass{article}
usepackage{subfigure}
usepackage{epsfig}
usepackage{cleveref}

begin{document}
    
    begin{figure}
        centering
        setcounter{subfigure}{0}
        subfigure[]{includegraphics{fig1}label{fig1}}
        subfigure[]{includegraphics{fig2}label{fig2}}
        subfigure[]{includegraphics{fig3}label{fig3}}
        subfigure[]{includegraphics{fig4}label{fig4}}
        subfigure[]{includegraphics{fig5}label{fig5}}
        caption{
            This is a figure.
            cref{fig1} first figure,
            cref{fig2} second figure,
            and labelcref{fig3,fig4,fig5} rest of figures.
        }   
    end{figure}
    
end{document}

This is the output I am getting:

But I want it to look like:

Fig1. this is a figure. (a) first figure. (b) second figure. (c-e) the
rest of figures.

In the following example, package subcaption is loaded instead of subfigure, and epsfig is replaced with graphicx. Recent version of graphicx can handle eps figures automatically. Also,

subfloat is used instead of subfigure since subcaption defines the latter as an environment,
option labelsep=none is used to center the caption of subfigure (since it has empty caption title), and
option subrefformat=parens is used to make subref{fig1} produce (a) instead of just a.

At last, dummy images provided by mwe package are used since I don't have image files fig1, fig1, ... .
documentclass{article}
usepackage{graphicx}
usepackage{subcaption}
%usepackage{hyperref}
usepackage{cleveref}

captionsetup[sub]{labelsep=none, subrefformat=parens}
crefrangelabelformat{subfigure}
  {(#3crefstripprefix{#2}{#1}#4--#5crefstripprefix{#1}{#2}#6)}

begin{document}
    
begin{figure}
    centering
    subfloat[label{fig1}]{includegraphics[width=3cm]{example-image-a}}quad
    subfloat[label{fig2}]{includegraphics[width=3cm]{example-image-b}}quad
    subfloat[label{fig3}]{includegraphics[width=3cm]{example-image-c}}
    subfloat[label{fig4}]{includegraphics[width=3cm]{example-image-a}}quad
    subfloat[label{fig5}]{includegraphics[width=3cm]{example-image-b}}
    caption{%
        This is a figure.
        subref{fig1} first figure,
        subref{fig2} second figure,
        and labelcref{fig3,fig4,fig5} rest of figures.
    }   
end{figure}
    
end{document}

If you prefer labelcref from cleveref than subref from subcaption, see answers in question Combining cleveref and subref.
