Inside a script *element*, yes. You can have as many as you like.

Because there are errors in the and HTML - *always* start with valid
HTML. The W3C HTML validator lets you paste markup directly into the
validation form.

The language attribute is deprecated, remove it. Keep type.

Don't use HTML comments inside script elements, they are useless.

The result of the document.write will be placed immediately after the
script element. It is still inside the head, the browser isn't supposed
to display any content in the head so the browser must decide whether to
employ error correction and end the head and display the text, or
continue the head to the closing tag and not show the text.
Whatever choice is made may be inconsistent across different browsers.

This is a meaningless script statement. To use HTML comments at all,
the closing tag should be quoted:
// -->
But just don't use them.

Comments as above.

What is in the external file? You should have a title element inside
the head. Putting one right at the top might encourage error correction
to move the closing head tag up higher and move the body up too -
causing the text written by document.write to be displayed (or not).

Here you are missing the closing quote after language="JavaScript
That will cause a variety of errors, essentially reversing the sense of
following double quotes.

It is legal to quote new lines, but much preferred to use concatenation:
document.write("The purpose ..."
+ "<br>1. Use..."
+ "<br>2. To..."
);

Don't use XHTML style empty element tags in what is HTML (despite the
missing, required DOCTYPE element).
Forward slashes "/" within document.write strings should be quoted
because they should indicate the close of the script element, most
browsers tolerate them regardless.

Fix those errors and apply to the rest of the page.
