In the notes section, it says "Rwy 12 Straight-in and Circling and Circling to Rwy 3R/30 NA (not authorized) at night."

2) What does the "A" in the black triangle, located in the notes section, mean?

The "A" means non-standard IFR alternates exist. When an alternate airport is required, standard IFR alternate minimums apply. Precision approach procedures require a 600' ceiling and 2 statute miles visibility; nonprecision approaches require an 800' ceiling and 2 statute miles visibility. However, those minimums are higher at Prescott, and vary based on your aircraft, as well as the approach you are capable of flying.

3) If you fly the 10 DME arc using R-259 as the initial approach fix, do you need to complete a procedure turn over the Drake VOR?

The arc says "NoPT", meaning you should not fly a procedure turn in this scenario.

4) You cross the VOR inbound and descend to the MDA (straight in, RWY 12). How high above the touchdown zone are you?

You are 516 feet above the touchdown zone. This altitude is marked in the altitude block (S-12), in the bottom of the approach chart.

5) You don't have DME, and you're crossing the VOR inbound for the approach. Your ground speed is 105 knots. How long will it take you to reach the missed approach point?

As you can see from the bottom of the airport diagram, if 90 knots groundspeed takes 2:36, and 120 knots groundspeed takes 1:57, then 105 knots groundspeed will take 2:16. (120 knots + 90 knots / 2 = 105 knots, 2:36 + 1:57/2= 2:16)
