Is it necessary to use meta tags on every page of a site?

Navigation

I created a multipage website. And my question is this: You need to put the < meta > on all pages of the site? (Biography, contacts, etc ...)

I'm using the following tags on my site (mostly in index): 

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

<meta name=“title" content="">
<meta name="description" content="">
<meta name="keywords" content="">
<meta name="author" content="">

In addition to these tags, for search engines, or something else, do I need to add any more tags? 

<meta http-equiv="X-UA-Compatible" content="IE=edge">

What would this be? What's the use? Is it necessary to place? It has this tag also in some of the codes I've seen. 

<meta http-equiv="content-language" content="pt-br">

And I've already put lang: en within the HTML tag.

Could anyone help me?

Is the following you use what you want in your site, now if it is necessary to use in all the files? yes, it is necessary but it is not mandatory I will give an example to <meta charset="utf-8"> is for the type of characters that will use if not put that the page will not recognize certain characters.
