I'll leave Anon to 1 and 3, I'll answer to the best of my ability 2 and 4.

2. My theory is that only females can be Alicorns, as so far, there is little to no evidence that supports such a male Alicorn existing. Maybe they existed at one point, but they most likely do not anymore.

4. Well, we didn't hear about Blueblood's official existence until the last episode of the first season, Cadence is probably the same way. About Shining Armor, though, we also didn't see Rarity's parents in that episode. My little theory (I really didn't mean to parody the title, there) is that Blueblood is the older sibling and, as such, must have been in school, or out working during the time of Twilight's admission exam.
