If you got the Enhanced Edition, Baldur's Gate 2 had 22, 23 if you count Clara but that's a special case. The first game had 25, plus an additional five for the tutorial and four more added in the Enhanced Edition. Baldur's Gate 3 doesn't even have half that number. Admittedly, it's not a fair comparison as Larian had to put a lot more work into the 10 companions we have in BG3 than Bioware probably put into all the companions in both previous games combined.
Most of BG2 companions had very limited personality and involvement aside from their personal quests. Compare Edwin and Mazzy for example.
