Is there a way to write and i/else statement within document.write?

I wish this help you Use the conditional operator. If the random amount is one, don't add an s, otherwise add an s:
code :
var amount = ["zero", "one", "two"];
var fruit = ["apple", "banana", "orange", "grape"];

var rand1 = [Math.floor(Math.random() * amount.length)];
var rand2 = [Math.floor(Math.random() * fruit.length)];

document.write("I have" + " " + amount[rand1] + ' ' + fruit[rand2] + (amount[rand1] === 'one' ? '' : 's') + ".");
var amount = ["zero", "one", "two"];
var fruit = ["apple", "banana", "orange", "grape"];

var rand1 = [Math.floor(Math.random() * amount.length)];
var rand2 = [Math.floor(Math.random() * fruit.length)];

document.write(`I have ${amount[rand1]} ${fruit[rand2]}${amount[rand1] === 'one' ? '' : 's'}.`);
amount[rand1] === 'one' ? '' : 's'

wish of those help Javascript treats every new line as separate statement and You are using multiline string
so use \ at each end of the line in string(..) to make it one string

document.write stylesheet if statement that will always be false

I wish did fix the issue. There is one circumstance that this would make sense, though it is still probably messy - If the server would print a value there so that it it won't be equal, then the stylesheet will be used.
So, on the server in php, it might look like this:
code :
echo "if('{$someVar}' != '')" 
if('foo' != '')
    {
        document.write("<link type='text/css' rel='stylesheet' href='style.css' />");
    }
if($someVar != '') echo "<link type='text/css' rel='stylesheet' href='style.css' />";

Return statement not working, with document.write

Hope this helps Javascript has function scoping, which means that any variables declared in a function can't be accessed outside of that function. return added returns the value of added, not the variable added itself. If you want to use that value, you need to put it in a variable that was declared outside the function:
code :
function first(){
    var now = new Date();
    var first=Math.round(now.getMilliseconds()/20);
    var second=Math.round(now.getMilliseconds()/30);
    var added=first+second;
    return added;
}
var firstResult = first();
document.write(firstResult);

IF OR statement var = true, then write document

To fix this issue don't use document.write(); You have to create a new script element and add it the DOM.
code :
var isChrome = !!window.chrome && !!window.chrome.webstore;
if(isChrome){
  var s=document.createElement('script');
  s.src='source_to-Your_JS.js';
  document.head.appendChild(s);
}

Is document write the preferred way to write html to a third party site for corporate branding?

it helps some times You don't need to document.write(); in order to inject code into the head. If they embed your remote JavaScript file into their page, anywhere, you should be able to just append a script/style elements to the head.
code :
 var myScript = document.createElement('script');
 myScript.setAttribute('src', '...');
 myScript.setAttribute('type', 'text/javascript');
 document.getElementsByTagName('head')[0].appendChild( myScript );
<script>
  (function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){
  (i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),
  m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)
  })(window,document,'script','//www.google-analytics.com/analytics.js','ga');

  ga('create', '...', 'auto');
  ga('send', 'pageview');

</script>
