This depends on the developer. Sometimes a developer will develop applications exclusively for Android or exclusively for iOS. But you can usually find the same app or a similar app regardless of whether you own an iPhone or an Android phone. As for running an app built for iOS on Android, no. Android uses Java for its apps and iOS uses Objective C. Very different programming languages.
No, iOS apps are developed in a different language to Android apps and aren't directly compatible. In multiplayer mode however, you can play with other users regardless if they have an Android or iOS device.
I have a iPod Touch and an android phone and I prefer android. Android has more customization like live wallpapers, widgets, a home screen iOS is much more restricted you couldn't until iOS 4 where you could change the wallpaper, iOS is only good because it has x1.5 the amount of apps that android has.
IOS and Android do not work with HTML. They have completely different programming to work with.
Installing Android apps on IOS or vice versa is impossible unless the developer releases the app for both platforms. This is because IOS and Android are written in two completely different programming languages. Edit: You can install iOS apps on android with an app known as Cycada. Find it here: gg.gg/3p3gu As far as I can tell, is not available for download, though.
No, it is Android OS only. No similar app exists for iOS.
No, iPod touch is not an Android. iPod touch runs on Apple's iOS operating system while Android is different Operating system.
There is a high likelihood that there will be a Sonic the Hedgehog 3 for Android and IOS.
No
