Using a program to copy a player's input to multiple clients simultaneously is acceptable. The reason why is because the actions themselves are not automated (there is still, essentially, a player commanding all five characters - just all to do the same thing).
Now, if a program was being used where a player had to supply minimal effort to control or fight with the characters, that may be considered botting and would be a violation of our policies.
