Dan Gun, the only version I have ever known has a low section then a high section block on the first move only the pattern has 24 movements, adding 3 more low section blocks would bring the total to 27.
Hwa Rang - I was taught to punch straight and only 1 elbow with the other arm just coming back to the hip. The pattern started from the C stance with both hands crossed over in knife hands.
The 360 jump can be for either a leg attack with a staff or a double sweep with the legs. The pattern as a whole does not necessarily represent an entire attack sequence it can represent a series of smaller attack sequences strung together to form the pattern. The U-shaped block is more of a snatch the staff out of the hands of the attacker kind of thing. The 360 jump spin may represent the start of the next sub-sequence where you swing your front leg out of the way and then see the second leg sweep, say a spinning heel sweep, and jump off the standing leg. Because your first leg is turning away from your attacker landing straight down may cause you to land side on so you continue your momentum by spinning around and landing in a knife hand guarding block in a left back stance. You are not spinning around in mid air to see what the other guys are up to as you should already be aware of them with your peripheral vision.
I hope this answers your questions.
