There are a few things you can do. 1) You can take it to Verizon and they will activate your iPhone 5 for you, 2) Connect your iPhone 5 to your computer and iTunes should automatically activate it, and 3) take it to your nearest Apple Store and they can activate it for you (But I'm not 100% sure on the third option I've given you). Good luck.
Great question! It's important to be able to activate your replacement device. I can help. Here is a link that will walk you through activating your replacement device http://vz.to/OJjEhb . Have a great day!
