...would indicate 9mm is not an "easy/jog" for the long runs. I would recommend you use 5k+3mins i.e. closer to 10mm for at least the first half of the long runs, and, if you feel ok, do the second half faster, accelerating evenly towards the 9mm you first posited.
"Tempo" has many different meanings. Looking at the schedule, the tempos are structured as intervals, so somewhere between 10k and HM pace looks right. 7:30 would be ok.
"Fast" in the schedule looks like 5k pace imho.
Remember, there is a big slope-off in your times per distance, so you're better off doing more miles, more slowly, than the schedule asks, rather than smashing out fast tempos and short intervals. You need more endurance, not speed, to hit your goal Mara time.
