Avoiding content-type overkill: 5 slightly different pages = 5 different content types?
Answer is it depends.

How often is the content in these nodes being updated? Does the content in the different fields need to be used in tokens, views, etc?

If it's never updated OR if you can use wysiwyg to edit the body to position things where they need to go and make it easily editable then use one node type.

If the info needs to be put into fields so views/tokens can pull bits out of the nodes then creating fields for those values is important.
