No 4 is an LED I think (different lead length to denote anode/cathode- or possibly a photodiode? Maybe an IR receiver/transmitter

If that's correct, then the major clue for me was the two plastic domes on either side, which I think are designed to focus the LED light towards the viewer...

Damn, I was studiously ignoring this thread. Now I've gone and read it.
5 looks to me like a modern LED strip. The kind of thing you put on the bottom of your kitchen wall cupboards to cast light on your worktops.

Does it fit inside something for position sensing?

Answers so far:
9. It is not for a roller blind. The winders for roller blinds are usually quite simple and consist of little more than a pulley attached to a spigot that pushes into the end of the roller, and a guide that looks similar to the right-hand side of the object in the photo. It is not for a Venetian blind but you are getting close.

Not part of an encoder.

That is an interesting guess.

You may not know that it exists. If you keep guessing, I will leave more clues.
Most households had one.

4. The LED:
This radiates in two directions and is used with two photodiodes.
5. This is a thick paper tape with two metal strips on one side.

Well, fridges and tumble driers have mechanical light/power switches (and it's not an interlock anyway)
Not anywhere hot (oven , toaster) I assume
Washing machine drum speed?
