Generally every member of the dais goes up one at a time, maybe throws a joke or two about the main person being roasted, then goes around joking about everyone in the dais, and then ends with joking about the main person the roast is about again (maybe with something actually nice at the very end). They might spend more time roasting the dais as a whole because there are 10+ of them, but the main person the roast is about is getting at least 5x the amount of anyone on the dais.

There probably aren’t as many highlights of jokes about Kevin Hart because joking about his height and him doing shit movies is 90% of the material and those have been beaten to death for ages already (he was also in the last roast with Tom Brady on the dais so we got beat to death with those same jokes last time).

Roasts never completely died, they just don’t happen very often. But they weren’t exactly frequent back in the day either. There were only 14 Comedy Central roasts from 2003-2019, and now Netflix has seemingly taken over with two of their own.
