How to modify the name of a country?

Assume i have this HTML code:

<div class="list-select-options">
    <input type="text" id="country">
    <input type="hidden" id="country_code">
    <i class="fa fa-sort"></i>
</div><!-- .list-select-options end -->

And this js code:

$("#country").countrySelect({
    defaultCountry: "gb",
    onlyCountries: ['eg','gb'],
    preferredCountries: false,
    responsiveDropdown: true
});

So how to change for example United Kingdom to England?

You could create an instance of the input, set the default value to the selected country, and leave only that country on the list, @iamkarsoft.

The latest version (v2.1.0) now allows you to set the localized name of a country (see the localizedCountries option, documented on the README). This will allow you to override the names of countries you wish to change.
