Is it possible to work application, which developed for 8.1 OS, in Phone which have 8.0 OS?
As far as I know you can't. You could only deploy 8.1 apps on a device which is updated to 8.1. It's just a matter of updating the 8 OS. But after the 8.1 update you could still deploy WP8 apps too.

I'm building a Windows 10 UWP app, and would like to know if it will run on Windows Phone 8.1 and/or Windows 8.1 Desktop. Windows 8.1 is still quite prevalent, and I would like to be able to reach these users with my app.
Windows 10 apps can only run on Windows 10 (and newer). If you want to target 8.1, you have to build a 8.1. A 8.1 should run on Windows 10 without any problems.
I can't find any SQLite.Net.Platform library that works with Windows Phone 8.1.
These are not working:
https://www.nuget.org/packages/SQLite.Net.Platform.WindowsPhone8/
https://www.nuget.org/packages/SQLite.Net.Platform.WinRT/
https://www.nuget.org/packages/SQLite.Net.Platform.Generic/
https://www.nuget.org/packages/SQLite.Net.Platform.Win32/
Any workaround?
WinRT platform is compatible with Windows Phone 8.1 projects. You can copy the sources to your platform specific project and instantiate the connection using SQLitePlatformWinRT class.

I installed the last version of visual studio to target windows phone 8.1 OS. After the installation I figured out that the 8.1 OS was not yet released and I couldn't deploy my application on my device. Can I target the windows phone 8.0 version when building the application?
Yes you can. Go to your project properties and there on your application tab, you can select the target OS.
Select This Project Template & It will prompt you to select your targeting Windows Phone OS
But Once you have targeted 8.1 you can't deploy on a 8.0 device or emulator.
