Where did Thanos's army at the end came from?

Ok, so Thanos travels with his ship from 2014 to 2019, although the bracelet which they had was meant for just one person to time travel? They only have this one red thingy, which Cap and Tony went for in 1970, how did they bring the whole ship? Ok never mind.

So where did the entire army come from? Thanos's minions and the army were defeated in Infinity war, but in 2019 they are all alive again? How? Did they travel from 2014 to 2019 with Thanos? This just does not make any sence.
