The photos have been uploaded from my iPhone 5 to iCloud photos beta.
O.K., so your photos are already in your iCloud Photo Library (Beta) and thus, stored in iCloud.
You can create an album from them in Photos on an iPhone, iPad with iOS 8, but such an album would just group your photos and not add any safety, since an album only references the photos that are already in iCloud.
Your Mac can only access iCloud Photo Library (Beta) and download the photos using the iCloud Photos (Beta).app on the page: https://www.icloud.com, unless you are a Beta tester for the Mac Photos.app.
You can however create an additional Shared album by sharing the photos using the Photos.app on one of your iOS devices, see: iCloud: iCloud Photo Sharing FAQ
