Built-in functions (Google Spreadsheet functions) have nothing to do with your triggered functions (made by you). You're complicating the explanation with 2 things that have nothing in common. Of course Google functions will work!

Please explain better your functions, are they triggered by what? onEdit, onOpen, a menu? What protected ranges have to do with it? Does your functions work if you remove the protection of your ranges?

[edit]

Simple event handlers (like onEdit) have limited permissions by design, you probably need to set a installable on edit trigger. Please check out this other answer I gave.
