Thanks Dan, The 4th one - rubus - it doesn't get any fruit on it. When I look up rubus I see discussion of blackberry. Is it the same family? Thanks!
#4 looks like a very young Rubus spectabilis, a native shrub in your area. It will only get fruit on if you leave it to get full size (approx 2 metres tall, with two-year old stems). There are hundreds of species in Rubus; it includes blackberries, but also many others as well.
