Answer 1

ASP (Active Server Pages) is a server-side backend, you can only code asp scripts with VBS (Visual Basic for Scripting). It is no longer supported by Microsoft.
ASP.Net is the younger brother of ASP, it runs on, and supported by the .Net framework, and supports any language supported by .Net framework.
.Net Core
quoted from http://www.c-sharpcorner.com/article/difference-between-net-framework-and-net-core/
.NET Core is the new open-source and cross-platform framework to build applications for "all" operating system including Windows, Mac, and Linux. .NET Core supports UWP and ASP.NET Core only. UWP is used to build Windows 10 targets Windows and mobile applications. ASP.NET Core is used to build browser based web applications.
Web API? I have no idea, but API stands for "Application Programming Interface".

Answer 2

in backend, you can use web api. I work with web api for more than 2 years in backend dev role.
In angular (or any fontend such as android app, ios app ... ) can call web api with http request.
web api for request and reponse data. To work with sql server you can use entity framework (included in .net framework)
more info: .net framework have various supporting for backend and fontend.
