Android version 2.3 is codenamed Gingerbread. Android likes to codename its versions e.g. 2.2 is froyo
No there isn't any episodes running with Android actually, it's termed as versions and currently the latest version of Android is 5.0 Lollipop !
Yes, the HTC Thunderbolt runs android 2.2 Froyo. One of the newest versions.
Android in general can be referred to the company under Google that develops the operating system and devices. Android KitKat is the codename for one of many versions of Android's operating system, version 4.4 in this case.
It's possible if the apps package is backwards compatible to earlier Android versions.
Not necessarily. A number of apps can run on earlier versions of Android (ex: Android 2.0--Eclair). It's up to that particular app developer if they want to release an app that supports older Android versions. However, with the number of devices still supporting an older Android OS dwindling, it would be no surprise if a developer may no longer support an older OS.
You wait for the OTA update. Not all Android phones can run all versions of Android, so you may be waiting for something that isn't going to happen if you have an older handset.
Microsoft Silverlight currently does not work on Android devices. It will work on OSX and various versions of Windows. The Android developer community is working on it though.
Android Ice Cream Sandwich is next version of android OS. It will converge the formerly disparate phone and tablet versions of the OS. That means, it can work on both tabet PC and smartphone.
