Question

Html

Answer 1

Your question is not clear

Answer 2

Each html element can have exactly 1 id. Maybe you mean css classes? Or do you want to attach 2 javascript functions to the same html element?

Please clarify and link your code.

Answer 3

The ID must be unique and used once on the entire site. For your purpose, it's better to use a class:
<button class = "one"></button>
<button class = "one"></button>
