They say it's $5 for 5 devices on their page, and that it works as a Tailscale exit node... is that not true?

Looks like you're right, you can add up to five devices for the same price.

You still have to choose those devices in advance though.

In advance, sort of. The devices can be swapped around at basically any time. There's a little lag for a device to get the config update enabling Mullvad on it IME, usually 30 seconds or so.
