Camera Roll to iCloud?

If I want to move any or all of my photos into iCloud will they stay there indefinitely?

Yes. As long as you keep them there and don't delete them.

How would I access them?

From the Photos app. Photos stored in iCloud continue to appear in the Photos app as normal. You don't need to do anything different.

what if I at some point got a new iPhone and cancelled the additional paid storage, would I lose them?

If you cancelled the paid storage, you would lose anything that exceeds the free 5GB space. But you should not really cancel it. If you get a new iPhone, your iCloud storage remains with you as it is tied to your Apple ID and not a specific device.

Your new iPhone would be able to access said storage, and the photos kept there by simply turning on iCloud Photos in Settings->Photos.

Also, to reduce the space taken up directly on the iPhone, you would need to turn on Optimize Storage in Settings->Photos (the Optimize Storage option, is only available after you turn on iCloud Photos).
