      );

The problem in your code is, you are referencing removeByLoginName but you are passing email ID to delete the user. so try the below code,

Deleting user by Email ID:

'use strict';  
var hostweburl;  
var appweburl;  
// Get the URLs for the app web the host web URL from the query string.  
$(document).ready(function()  
{  
    //Get the URI decoded URLs.  
    hostweburl = decodeURIComponent(getQueryStringParameter("SPHostUrl"));  
    appweburl = decodeURIComponent(getQueryStringParameter("SPAppWebUrl"));  
    // Resources are in URLs in the form:  
    // web_url/_layouts/15/resource  
    // Load the js file and continue to load the page with information about the folders.  
    // SP.RequestExecutor.js to make cross-domain requests  
    $.getScript(hostweburl + "/_layouts/15/SP.RequestExecutor.js", getuser);  
});  
function getuser()   
{  
    var executor;  
    var userEmail = "karthik@jagan.onmicrosoft.com";  
    // Initialize the RequestExecutor with the app web URL.  
    executor = new SP.RequestExecutor(appweburl);  
    executor.executeAsync({  
        url: appweburl + "/_api/SP.AppContextSite(@target)/web/sitegroups(6)/users/getbyemail('" + userEmail + "')?@target='" + hostweburl + "'",  
        method: "POST",  
        headers: {  
            "X-HTTP-Method": "DELETE"  
        },  
        success: function(data) {  
            alert("User Deleted successfully in SharePoint Group");  
        },  
        error: function(err) {  
            alert("error: " + JSON.stringify(err));  
        }  
    });  
}  
//Utilities  
// Retrieve a query string value.  
// For production purposes you may want to use a library to handle the query string.  
function getQueryStringParameter(paramToRetrieve) {  
    var params = document.URL.split("?")[1].split("&");  
    for (var i = 0; i < params.length; i = i + 1) {  
        var singleParam = params[i].split("=");  
        if (singleParam[0] == paramToRetrieve) return singleParam[1];  
    }  
}  

Deleting user by Login Name:

<script language="javascript" type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jquery/1.8.1/jquery.min.js"></script>  
<script language="javascript" type="text/javascript">  
    $(document).ready(function() {  
        var removeUserUrl = "/_api/web/sitegroups/getbyname('Employee')/users/removeByLoginName";  
        var metadata = {  
            'loginName': 'i:0#.w|SharePointHOL\\KarthikJagan'  
        };  
        removeUser(removeUserUrl, metadata)  
    });  

    function removeUser(removeUserUrl, metadata) {  
        $.ajax({  
            url: _spPageContextInfo.webAbsoluteUrl + removeUserUrl,  
            type: "POST",  
            headers: {  
                "accept": "application/json;odata=verbose",  
                "X-RequestDigest": $("#__REQUESTDIGEST").val(),  
                "content-Type": "application/json;odata=verbose"  
            },  
            data: JSON.stringify(metadata),  
            success: function(data) {  
                console.log(data);  
                console.log("User has been successfully removed from the SharePoint Group.");  
            },  
            error: function(error) {  
                alert(JSON.stringify(error));  
            }  
        });  
    }  
</script>
