Use an array to store a list of strings, not a string.  Also prefer a
more descriptive name than "list".  What is it a list OF?

Use an associative array to store a mapping from strings to values.

Also, don't use which(1).


#!/bin/bash
apps=(dragon cvlc rhythmbox totem-audio-preview radiotray)
declare -A found

for app in "address@hidden"; do
    if command -v "$app" >/dev/null; then
        found[$app]=1
    else
        found[$app]=0
    fi
done

And so on.
