How to execute a powershell file in batch repeatadly - powershell

Question

I have a question. With my batch program I want to call a powershell program to replace words. I tried it with batch, but in my files are very often exclamation marks and yeah...batch don`t like these. So I take my batch strings and put them into powershell. This works perfectly fine. But I want to repeat this with other words and there is my problem.
set /a loop=0
:inta
set /a loop=%loop%+1
call:DoReplace "%Torsten%" "%Torsten:~0,-1%%loop%" cache\%KlausDieter:~0,-5%%loop%%Rainer% cache1\%KlausDieter:~0,-5%%loop%%Rainer%
exit /b
:DoReplace
echo ^(Get-Content "%3"^) ^| ForEach-Object { $_ -replace %1, %2 } ^| Set-Content %4>Rep.ps1
Powershell.exe -executionpolicy remotesigned -File Rep.ps1
if exist Rep.ps1 del Rep.ps1
GOTO :wer
:wer
set installel=%errorlevel%
if %loop%==%count% goto fall
if %installel%==0 goto inta
:fall
set /a loop=0
:intal
set /a loop=%loop%+1
call:DoReplaceL "%Horst%" "%Horst:~0,-1%%loop%" cache0\%Bruno:~0,-5%%loop%%Rainer% cache1\%Bruno:~0,-5%%loop%%Rainer%
exit /b
:DoReplaceL
echo ^(Get-Content "%3"^) ^| ForEach-Object { $_ -replace %1, %2 } ^| Set-Content %4>Rep.ps1
Powershell.exe -executionpolicy remotesigned -File Rep.ps1
if exist Rep.ps1 del Rep.ps1
GOTO :werl
:werl
set installel=%errorlevel%
if %loop%==%count% goto falll
if %installel%==0 goto intal
:falll
When I call it a second time there come a error with: Argument "Rep.ps1" isnt available. Isnt it possible to do such things?
I am from Germany so sorry for the bad english.
Thank you for your help

My batch-code for search and replace was this. Maybe you will find a mistake to get rid of problems with exclamation marks:
set /a loop=0
:inta
set /a loop=%loop%+1
SET "quell_datei=cache\%KlausDieter:~0,-5%%loop%.cin"
SET "ziel_datei=cache1\%KlausDieter:~0,-5%%loop%.cin"
SET "suchen_nach=%Torsten%1"
SET "ersetzen_durch=%Torsten%%loop%"
IF NOT DEFINED suchen_nach (ECHO. Fehler: Die Variable suchen_nach nicht definiert^^!&GOTO :eof)
del "%ziel_datei%" >nul 2>&1
FOR /f "tokens=1,* delims=:" %%a IN ('type "%quell_datei%" ^| FINDSTR /n "^"') DO (
CALL :ers "%%b"
)
GOTO :wer
:ers
set "zeile=%~1"
if defined zeile set "zeile=!zeile:%suchen_nach%=%ersetzen_durch%!"
>>"%ziel_datei%" echo.!zeile!
GOTO :eof
:wer
set installel=%errorlevel%
if %loop%==%count% goto fall
if %installel%==0 goto inta
:fall
echo.
