Instead of text =
use text +=
but also close the input tags and only submit data to the text area on submit button.
Let me know if you need me to expand the answer.

The traditional button method does a good job of using one function to combine radio button inputs. I have made some adjustments to a copy of your code below. The output is treated as two strings. if you want them added or used as numbers the use the parseInt() method. GL
<!DOCTYPE html>
<html>
<head>
<title>Number For Word</title>
<script>
function text(){
var name;
var school;
var names = document.getElementsByName('name');
for (var i = 0, length = names.length; i < length; i++) {
if (names[i].checked) {
name = names[i].value;
break; } }
var schools = document.getElementsByName('school');
for (var i = 0, length = schools.length; i < length; i++) {
if (schools[i].checked) {
school = schools[i].value;
break; } }
document.getElementById("my").value = (name + school );
};
</script>
</head>
<body>
<textarea id="my"></textarea>
<p>What is your name?</p>
<input type="radio" name="name" value ="1">Krio</input>
<input type="radio" name="name" value ="2">Ayman</input>
<br>
<input type="radio" name="name" value ="3">Mohamed</input>
<input type="radio" name="name" value ="4">Halim</input>
<input type="radio" name="name" value ="5">Mariam</input>
<br>
<p>What is your school?</p>
<input type="radio" name="school" value ="1" >Future</input>
<input type="radio" name="school" value ="2">Glil</input>
<input type="radio" name="school" value ="3" >Magdy</input>
<br>
<input type="radio" name="school" value ="4" >San Gorgre</input>
<input type="radio" name="school" value ="5">San Mary</input>
<br>
<button onClick=text()>ok</button>

Only numbers appears in textarea because you're using only number as 'value' attribute of your radio button ^^
Try something like :
<input type="radio" name="name" value ="krio" onclick="text(this.value)">krio
... others solution exists, but this is the simplest one in this case.
Anyway, @Arcayno advice is right if you doesn't want that a new selected choice delete previous output, you need at least modify your text functions as this:
function text(name) {
document.getElementById("my").value += name+'\n'; // obviously, do same in atext() function
}
... the new line character appended will make each new clicked choice appended to a new line of the textarea.
However, if user click more than once choice in each radio group, all clicked log will persist: better way to handle each of radio group choice in their own log output element ;)
