1. I'm by no means a "multiverse expert" but from my understanding of multiverse theory there is an infinite amount of universes. I believe this would follow suit in the JoJo universe (or multiverse) as Valentine grabs countless alternate versions of himself upon death to replace him. He never seems to worry about running out of Valentines so there are probably infinte universes, or at least a very large amount.

2. The power of infinity comes from the idea that the spiral formed by a golden rectangle goes on for infinity and the perfect spin/rotation is simply harnessing this power. The way I see it, Love Train creates a gap in space in which Valentine is no longer affected by the surrounding universe. In a sense he is in his own tiny dimension in which nothing can get to him except for something that can cross dimensions (this would also mean he couldn't get out if he didn't have a dimension crossing ability). By coming into contact with Love Train's barrier, an attack or person/object is shifted to another location (possibly to other dimensions like you said due to D4C's abilities). Due to being able to harness the power of infinity, Tusk Act 4 and Ball Breaker are not bound by the laws of time and space, which allows the Stands to freely cross dimensions or move within frozen time.

Tbh this is a very complicated topic and I'm not even sure if I answered your question, but I hope this helps.
