Basically we're aiming for naps to be 1.5-2 hrs. If the nap is shorter than that, the next awake time will need to be shorter. So at 9 months, 1hr and 15 mins is probably a good amount of awake time (that includes feeding, changing, activity, winding down - everything from eyes open to eyes shut). If she naps for 1hr, I'd cut the next A(awake) down to 1hr. If she naps even less, bring the A down correspondingly.
From your routine above it looks like she's getting progressively more overtired as the day goes on. The first A is good, but for the next one (if she naps at 9.15 for an hour), she's awake 2hrs 45 mins which is way too long, and will make it much harder for her to settle. I would spend a few days trying to make sure she is never awake more than 1hr and 15-20 mins - and even less than that after a short nap - and see how you get on.
Re your cluster feed, I would drop the 9pm feed and just do the dreamfeed, it's not generally recommended to continue to cluster feed after about 6 weeks because it can encourage snacking. That might encourage her to take more at 11 too.
Hope that helps
