I have already purchased and installed Lightroom 5 a year ago. However on the Adobe website they offer Lightroom 5 and Photoshop CC as a package for $9.00. I was wondering if I purchased the monthly subscription if I could cancel and still use the Lightroom 5 program that I have installed if I decide to cancel.

At any point in time if you decide to cancel the Creative Cloud Subscription ($9.99 plan), you will still be able to use the Lightroom 5 standalone program that you purchased.
But with Creative Cloud subscription, you get free upgrade of Lightroom to the current version which is Lightroom CC/6. If you upgrade your catalog to Lightroom CC with the subscription then, you would not be able to downgrade that particular catalog to Lightroom 5 later on.
Let us know if you need any further assistance.
