The kills from the red trailer were for visial effect, but the rose petals are definately part of her semblance somehow. And we can't take anything from the trailer too seriously because it always ends up something else in the actual show.

The only way I think someone would gain another semblance is via the Uchiha method - rip the aura from another person's body.

I'd like to think that Semblances evolve as the hunter grows older. Ruby's speed turns into actual teleportation and Blake produces multiple clones that last more than a second.
