Answer 1

Are you selecting multiple Path elements first? I've loaded the code you posted in Blend and Unite is enabled. You have to select at least two Path elements for the Combine options to become enabled. Personally, I find it easier to select them in the Objects and Timeline panel and right-click to find the Combine menu.
Assuming that you are trying to turn this art into a single Path element, I can only say "good luck". This kind of operation can be very tricky. My bet is that the Path operations will not do what you actually want because overlapping elements combine properties as well as Paths. You'll lose detail of one element or the other if they overlap.
It seems then that Compound Paths would be the answer, but Compound Paths suffer from the same issue. Select all the Paths and use Path > Make Compound Path. On the surface this seems OK until you realize the black button in the center of the art is now white. When you think of it, this makes sense. You are asking a single Path to have multiple Fill properties, which it cannot do.
You can experiment with the other Path operations but they all enforce the same rules because in the end a Path isn't all that complex. The real question I would ask is "what are you really trying to achieve"? The only real reason to convert these all to a single Path is so that they can share the same properties.
If you tell me what problem you are trying to solve maybe we can find a solution. The elements are already grouped together (in Layer_2). If you are looking to make this a reusable graphic on other screens, I would group Layer_2 into a ViewBox and then export the ViewBox to a UserControl (right-click > Make Into User Control). My guess is this is what you are actually after.
