Yeah I'd agree with the above post. Definately Blackberries in the first and last. You must battle them relentlessly to rid your yard of them in the PNW, though I've kept a couple and keep em pruned back, the berries are good as long you know they haven't been sprayed.
Any unwanted ones you gotta dig up as much of the root as can and tear them out. Don't add any of it to your compost piles, because unless it's a very hot pile enough will most likely survive and apprecate it's new space when you go on to use the compost. I dig and tear the fence line of my house every spring, any that survive after that I keep them cut back and unless it's one of the two growing over my fence in one corner of the yard that I freely pick from, I prune them back once they start to flower, This helps cut down on the ones you gotta pull next year. But it took me about 5 years of doing this to get some controll over them without sprays.
The others are most likely Rhodies (though the nuts are kinda making me think it may be something else).. They're another easy decoritive plant here in the Northwest. Great blooms in the spring, though a bit of sticky mess to pick up after their flowers have dies off. They can be tough to remove if you're so inclined beacuse they root themselves in pretty deep. And if they've been there awhile, you can cut them back 100% and they'll simply start all over from scratch (I tried this once hopeing it'd kill it and a season of rot would make it easier to remove the stump).
