Remove the first link
element. It tries to refer to a font file as a CSS file, and this won’t work.
The second link
element is correct, but it only makes the Felipa font available. It does not make any element actually use it. You need to add code like
<style>
* { font-family: Felipa; }
</style>
If you still have problems with some hosting service (which is what “c9.io IDE” seems to refer to), consult the instructions given by the service provider.
