The last one is maybe Hibiscus moscheutos? Looks like it will bloom soon and then it will be easier to identify.
Same with the middle one. Maybe Hibiscus 'Kopper King'? Hard to say until it blooms. On the red leaved hibiscus varieties, leaf color can largely depend on the amount of sun & leaf shape can change with maturity (can develop more & deeper lobes), so depending on the age of this plant and the amount of sun it receives, positive ID could be tricky. When it blooms, repost pictures.
