Getting brew/homebrew applications to work properly on M1 ARM Apple Silicon

Hi. I am new to the Apple Macintosh yet a long-time user of the UNIX family of operating systems and desktop environments. (I am not coming from Microsoft Windows) It naturally came to me to install brew/homebrew (is there a difference ?) to enjoy extra software packages from the command line, however I have only been able to make a few of these work.

Here are the relevant brew command lines :

 ~ % cat .zsh_history | grep brew
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
    echo 'eval "$(/opt/homebrew/bin/brew shellenv)"' >> /Users/sylvain/.zprofile\
    eval "$(/opt/homebrew/bin/brew shellenv)"\
brew install --cask youtube-downloader
brew install rtorrent
brew install rar
xattr -l /opt/homebrew/bin/unrar\
xattr -d com.apple.quarantine /opt/homebrew/bin/rar
xattr -d com.apple.quarantine /opt/homebrew/bin/unrar
brew cask install vlc
brew install vlc
brew tap kde-mac/kde https://invent.kde.org/packaging/homebrew-kde.git --force-auto-update\
"$(brew --repo kde-mac/kde)/tools/do-caveats.sh"\
brew install kde-mac/kde/elisa
brew upgrade
brew install lftp
brew install --cask kid3

Only vlc and I think maybe also lftp have been working out of the box.

What may I be doing wrong for the following ? :

· rar - how can I integrate it to the Finder ?

· rtorrent : I seemed to gather from peering through the forums that it often fails to compile ?

· youtube-downloader : displays a warning window that Apple cannot check for the absence of malware and the app has to be updated.

· regarding elisa and kid3, I guess I should turn to the relevant KDE/Plasma community.
