How can I rename the theorem environment to proposition? In other words, I would like to print:
Proposition 1 instead of Theorem 1/Lemma 1, etc
Thanks in advance
PS: I am using koma-script article
[Tex/LaTex] rename theorem environment to proposition

From your code, it seems that you want each of the theorem-like environments to inherit the subsection counter. As such, I have used
\newcounter{dummy}
\numberwithin{dummy}{subsection}
in the below.
Note that you can use
\newtheorem{example}[dummy]{Example}
which tells the newtheorem command to make the example counter inherit the dummy counter, but not
\newtheorem{example}{Example}[dummy][subsection]
as this is undefined.
Here's the complete MWE:
\documentclass{article}
\usepackage{amsmath,amssymb}
\usepackage[thmmarks]{ntheorem}
\newcounter{dummy}
\numberwithin{dummy}{subsection}
\theoremprework{\setlength
\theorempreskipamount{10 pt}\setlength\theorempostskipamount{10 pt}}
\theoremstyle{plain}
\theorembodyfont{\upshape}
\theoremsymbol{\ensuremath{\clubsuit}}
\theoremseparator{:}
\newtheorem{example}[dummy]{Example}
\theoremstyle{plain}
\theorembodyfont{\upshape}
\theoremsymbol{\ensuremath{\blacklozenge}}
\theoremseparator{:}
\newtheorem{remark}[dummy]{Remark}
\theoremprework{\setlength\theorempreskipamount{10 pt}}
\theoremstyle{plain}
\theorembodyfont{\slshape}
\theoremsymbol{}
\theoremseparator{:}
\newtheorem{theorem}[dummy]{Theorem}
\theoremstyle{plain}
\theorembodyfont{\slshape}
\theoremsymbol{}
\theoremseparator{:}
\newtheorem{prop}[dummy]{Proposition}
\theoremstyle{plain}
\theoremheaderfont{\upshape \bfseries}
\theorembodyfont{\slshape}
\theoremsymbol{}
\theoremseparator{:}
\newtheorem{corollary}[dummy]{Corollary}
\theoremstyle{plain}
\theoremheaderfont{\upshape \bfseries}
\theorembodyfont{\slshape}
\theoremsymbol{}
\theoremseparator{:}
\newtheorem{lemma}[dummy]{Lemma}
\begin{document}
\section{Section}
\subsection{SubSection}
\begin{theorem} Hey
\end{theorem}
\begin{lemma}I
\end{lemma}
\begin{prop}Just
\end{prop}
\begin{remark}Met
\end{remark}
\begin{example}You
\end{example}
\subsection{SubSection}
\begin{theorem} Hey
\end{theorem}
\begin{lemma}I
\end{lemma}
\begin{prop}Just
\end{prop}
\begin{remark}Met
\end{remark}
\begin{example}You
\end{example}
\end{document}
The \newtheorem construction offers two optional arguments. The first one fixes your numbering. In this case it means that proposition should use the same counter as theorem.
\documentclass{article}
\usepackage{amsthm}
\begin{document}
\newtheorem{theorem}{Theorem}
\newtheorem{proposition}[theorem]{Proposition}
\begin{theorem}
1+1=2.
\end{theorem}
\begin{proposition}
1+2=3
\end{proposition}
\end{document}
