Nope, there is just one Thanos. Infinity Finale happened before the Secret Wars and dealt with the death and rebirth of a single universe, Earth-616. After its restoration, Thanos and the alternate Adam Warlock saw what became of it in the future, and the alternate Adam Warlock went on to become the new Living Tribunal. Thanos was killed in the Secret Wars, but wasn't brought back along all the rest, and thus was left stuck outside the entire Multiverse, where he fell in love with the concept of nothing. As you probably know, he eventually entered the new iteration of the Multiverse and decided to show people how much love he has for nothing.
