You technically can order the Pipelines if that is what you really want to do but it will mean they all run at least partially depending how you built them. You have the ability to call other Pipelines from your current Pipeline so just do that until your last one. Combine Lauras idea with this one and make the very last Pipeline update a checkbox or date/time field to say it has been completed.
Also it feels like maybe it would be better to combine all your Pipelines into a single one though. You can do conditional statements within Pipelines so that they check a record for something and take action if it finds whatever you list, or it could skip that part. On the Pipeline instead of dragging something over simply hit "insert a condition" and you can choose something. So you could say like "If Question #1 is not blank, execute these steps", etc. But it may not make sense for you in this case, just an idea.
