How should I structure my application?

There is no definitive answer to this question. The answer depends on the scale of your application and the team that is involved. To be as flexible as possible, Fiber makes no assumptions in terms of structure.
Routes and other application-specific logic can live in as many files as you wish, in any directory structure you prefer. View the following examples for inspiration:

How do I handle custom 404 responses?

If you're using v2.32.0 or later, all you need to do is to implement a custom error handler. See below, or see a more detailed explanation at Error Handling.
If you're using v2.31.0 or earlier, the error handler will not capture 404 errors. Instead, you need to add a middleware function at the very bottom of the stack (below all other functions) to handle a 404 response:
Example
app.Use(func(c *fiber.Ctx) error {
return c.Status(fiber.StatusNotFound).SendString("Sorry can't find that!")
})

How do I set up an error handler?

To override the default error handler, you can override the default when providing a Config when initiating a new Fiber instance.
Example
app := fiber.New(fiber.Config{
ErrorHandler: func(c *fiber.Ctx, err error) error {
return c.Status(fiber.StatusInternalServerError).SendString(err.Error())
},
})
We have a dedicated page explaining how error handling works in Fiber, see Error Handling.
