monitor command outputs in separate windows within a terminal

For a list of input text, I want to execute a repetitive command using each element from the list. In addition I also need to monitor the results of each of these commands in parallel. So I am looking for a solution to display the repetitive commands output in separate windows in a single terminal console; probably need a form of terminal multiplexer? So far I have the following: for i in command1 find msgs/Poly; do echo command2 echo "$i" ; multitail -l 'command2 echo "$i"' ; done which seems to open only one window at a time.
