Eh, yes and no. Red Alert 1 is part of both the Red Alert and Tiberium series. One ending results in RA2 and the other in Tiberian Dawn (C&C '95) but there’s no consensus on which ending leads to which game. I think that the Allied ending leads to TD and the Soviet ending leads to RA2, but there are arguments the other way, too.
That’s just the Red Alert series, but ok.
