Is it possible to run Windows Phone 8 emulator on Windows 8.1 standard edition (not 8.1 Pro)?
I know that normally the emulator requires Hyper-V which is not available in non-Pro version but since Windows Phone 7 emulator works fine without Hyper-V maybe there is a way to run 8's emulator without Hyper-V as well?
I am a newbie for WP.My windows phone 7.1 application works in windows phone 7 but the application hangs when I open it in windows phone 8. I also want to know how to test the application for compatibility in both windows phone 7 and windows phone 8.Thanks in advance.
The applications built for Windows Phone 7.x should work on Windows Phone 8. However,some applications may not work properly and you should definitely test your application on Windows Phone 8 devices.
You could also maintain two versions of your application: one for Windows Phone 7 and one for Windows Phone 8. You will be able to upgrade Windows Phone 7 project to Windows Phone 8 project, but you cannot downgrade. The best thing to do is to create a new Windows Phone 7 project and move all files from the WP8 project to the new one.

Is it possible to upgrade a recent project that I started developping with windows phone 8 sdk and continue it with windows phone 8.1 or do I have to restart from scratch
If you want to target Windows Phone 8.1 (Silverlight Application) then you don't need to start from scratch, you will be able to upgrade from your Windows Phone 8 (Silverlight Project) but if you want to target Windows Phone 8.1 (New Universal App API's) then you will have to develop your application from scratch.
Here this will help you understand better Link

Will my app still run on Windows Phone 8 devices? Is Windows Phone Silverlight 8 the same as Windows Phone 8?
Yes, it is.
Windows Phone Silverlight 8 is the name given to Windows Phone 8 after the release of Windows Phone 8.1.
There is also Windows Phone Silverlight 8.1 and Windows Phone 8.1. The difference between these two is that Windows Phone 8.1 is compatible with Windows Store Apps, and Windows Phone Silverlight 8.1 won't be compatible with that.

I'm using windows 8.1 in frensh,but visual studio 2012 in english and I want to install Microsoft windows phone SDK 8 , but i could't , i tried many times but i have always the same error :Windows Phone Emulator is not compatible with this version of Windows.
What i should do please ,
What is your version of Windows 8.1? You need AT LEAST Windows 8.1 Pro or better to be able to run Windows Phone Emulators. If your version is a standard one, you cannot use the Windows Phone 8 emulators, as your windows doesn't have HyperV
