Can icloud be downloaded to android

No. There is no iCloud app for Android.

However you can access the iCloud.com website through the web browser on your Android device, or setup your iCloud email in the Android mail client.

You can use an internet browser (e.g., Chrome) and download data from iCloud by logging in to www.icloud.com. You can do that from any computer but if it is a mobile device be aware that iCloud.com is not optimized for mobile devices and you may need to force your browser to request the desktop version of the site.

No. Incompatible software and hardware.
