We had a situation where we wanted to build Windows Phone app with minimum compatible version Windows Phone 8.1. It makes uses of VOIP calls over 3G / 4G and Wifi.
I am unable to find whether Windows Phone 8.1 has full support for VOIP calls or not. Can anyone redirect me to right documentation or guidance if WP8.1 supports VOIP?
Please check this below link for VoIP capabilities of Windows Phone 8 https://msdn.microsoft.com/en-us/library/windows/apps/jj206983(v=vs.105).aspx
I'm trying to develop a VoIP application based on these solutions:
https://github.com/DoubangoTelecom/boghe & https://github.com/BelledonneCommunications/linphone-wp
Check these. I think it does.

Windows.System.UserProfile.Lockscreen is not available in the WinRT API for Windows Phone. Is it possible to programatically modify the lockscreen background of a windows phone device from a winrt app by some other means?
No. LockScreen providers are in the list of Windows Phone 8 features for which there is no Windows Phone Store equivalent. They are available only to Silverlight apps.
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 am developping application using windows phone 8 sdk and I wonder if this application can work on device that use windows phone 8.1?
Yes, Windows Phone 8 app can continue to run on Windows Phone version 8.1.
But there are some compatibility and breaking changes you can check here.
I am installing windows phone power tools.
I am getting emulators like emulator Windows Phone7.5, like that.
But i need a windows emulator like Emulator WXGA.
Please help me for this.
I would suggest that you un-install the SDKs, and then get the SDK for WP8 from the official site.
It has the WP7.5 support there as well, thus should work for both development purposes. Also do remember to check the Windows Phone Emulator for Windows Phone 8, do note the requirements for SLAT, DEP & that you need to have Windows 8 Pro or Enterprise 64 bit Operating System for the Hyper V to be present in there as well.
Is there Windows Phone 8.1 API to refer? This is because I want to develop the Windows Phone 8.1 application, but I don't know where to refer the API, since the Windows Phone 8.1 an 8 have a big different, so I can't refer to the Windows Phone 8 API.
There is two sets of APIs available on Windows Phone 8.1
Windows Runtime (MSDN), all APIs with a phone icon on the documentation page is available on WP8.1. This applies to the "Universal App" project types. Many of these APIs are shared with Windows Store applications (aka. Metro or Modern applications), allowing you to have the same code-base for both Windows and Windows Phone applications.
Silverlight (MSDN) applies to Silverlight 8.0 and Silverlight 8.1 APIs. There's no specific distinction on MSDN for 8.1 only APIs.
MSDN also have a mixed list of the two above for What's New in Windows Phone 8.1 (MSDN), primarily targeting the Windows Runtime features.
I would personally recommend writing Universal Apps (Windows Runtime), rather than sticking with Silverlight, unless you have a good reason, such as a VoIP application, or the wish to remain backward compatible with 8.0 users, while taking advantage of the new 8.1 features.
