Answer 1

<p id="fId"></p>
<script>
document.getElementById("fId").innerHTML="Say hell0";
</script>

you need to know about {innerHTML}

Answer 2

Wrong syntax

Answer 3

document.getElementById("id").innetHTML;
instead of
document.getELementById"id".innerHTML;
and you should use = "say Hi" after that
var myVar1 = document.getElementById("firstid").innerHTML;
myVar1 = "say Hi";
