If you are using windows server, then you can achieve this by a single machine. Here the concept of high density robots can be used.
You need 5 runtimes, for running 5 of them at a time.
Actually both of your suggestion is possible to do.
Its upto you to decide how your bot will be work
So if you wanna run all 5 bot at the same machine concurrently so I suggest you to have hi density server/robot
