Need help identifying volunteer plants. I live beachside in Daytona Beach & have two plants/trees or ? that showed up. I have no idea what they are, their care or even if I should keep them. The spikey one is slow growing & the tree/shrub is a fast grower. Any help is greatly appreciated.

It appears that the taller one is some kind of hibiscus. The shorter one is harder to identify, because it looks like so many different things. Does the small one have a particular smell to it?
