In Angel Beats, Kanade clearly entered the afterlife before even Yurippe did, yet Otonashi arrived later. Technically, Kanade must've died after Otonashi.
How is it possible that Kanade has Otonashi's heart?

Unfortunately, Angel Beats! doesn't go into much detail about the mechanics of the afterlife environment it takes place in.
However, if we assume that the series follows the basic concept of eternity, then a partial explanation can be given.
I drew up this little image of the three different timelines that are present in the series:
Key:
The green line is the (main) world timeline where the characters in the series lived their lives before they died.
The red line is the afterlife timeline where the characters went when they died and where most of the series takes place.
The cyan line is the alternate world timeline where (I presume) the characters in the series went after they've resolved their issues and regrets in the afterlife and moved on.
The white circles/ovals represent the time Kanade Tachibana spent on a timeline.
The blue circles/ovals represent the time Yuzuru Otonashi spent on a timeline.
The white lines represent Kanade's transition from one timeline to another.
The blue lines represent Yuzuru's transition from one timeline to another.
The ranges of the circles/ovals are rough estimates.
The (Main) World Timeline
The Afterlife Timeline
The Alternate World Timeline
Like I said, the series never really explains the finer details of the afterlife and what exactly happens when someone moves on. This is the best explanation I can give you at the moment. Perhaps some more light will be shed on this matter in the future.
I just saw the anime, and it got me puzzling for a while, but I had made up a somewhat believable explanation:
My proposed timeline:
The reason Otonashi didn't end up in the afterlife school upon death, is because he didn't really die with regrets. His own theory was that he simply "forgot" and thus ended up in the school, but that doesn't make much sense. Instead, he moved on, rested peacefully for a while, and then Kanade's wish brought him to the school.
In addition to Lunar Guy's explanation, my theory would be that, even though Yuzuru died first, the rate of their transition is different, it probably took Yuzuru a long time to transition between two timelines than what it took Kanade. That's why Kanade arrived first, rather than Yuzuru.
To support this, Kanade's regret was that she could not thank the person who gave her his heart, so I'd assume that some form of higher system craftily planned for Kanade to arrive first rather than Yuzuru, so that she could fulfill her regret and move on. Otherwise if Yuzuru arrived first, there would be a risk that he would move on first, making Kanade's regret unfulfilled, leaving her stuck in the Afterlife.
I have a different theory:
Opinions?
n.n
I propose a different solution.
What if time in the afterlife traveled in reverse, compared to the "real" word? Then all the characters would be able to die and immediately travel to the afterlife.
Note: When I re-watch the series, I will look for supporting facts. At the moment, this is only a theory.
This answer may be wrong, but possibly Kanade was in a coma awaiting a heart transplant. Yuzuru died a bit later and donated his heart to Kanade. It'd make sense because Kanade has Yuzuru's heart in her. The surgery must've failed and she ended up dying, so that's why she remains in purgatory.
That's how I understand it anyway.
I imagine the time it takes to transition into the after life = the number of regrets. The simpler the regret, the faster it takes to get to the after life. Kanade's regret was just to thank the person who gave her the heart, while otonashi'a regret is more complicated because he had no regrets, but he didn't know. Hideki came into the after life before Yui because his regret was just to catch a ball, while Yui was multiple things she saw on TV. Time of death does play a role, but I think second to the kind of regret. Yui could have died before Hideki.
This is the fitting interpretation for me:
Remember when Otonashi signed that organ donor card before he died? Angel was given his heart because she needed it and came to the afterlife to thank Otonashi for his heart.
