why you need to add multiple command nk?

You are right. As I say in my answer -- no reason for that. This is just a very inadequate question; OP needs to learn the very basic stuff but is writing XAML instead.

Solution 1

You never need "multiple commands". You just need several different methods called on a click, say, methods A, B and C. A "command" is actually a delegate instance. It should be some named or anonymous delegate instance with the following simple implementation: call A, B and C. :-)

Simple, isn't it?
