which meta tags are used by google and bing search

I am working on an asp.net mvc web application, and i am using a web templete that have the following metadata:-

<html>
<head>   

    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">

    <meta name="format-detection" content="telephone=no" />
    <meta name="description" content="Your description">
    <meta name="keywords" content="Your keywords">
    <meta name="author" content="My web Site">
    <title>Edama - @ViewBag.Title  </title>

now i have the following questions:-

will these meta tags be treated the same inside google & bing search engines?
what is the purpose for providing content="telephone=no" how it will be understood by google and bing search engines ?
final question. on some website when i search for them , i got links such as About, contact, etc.. so how i can provide these info to search engines ?
