The last two look like a walnut or a hickory. Do you have those growing nearby? If so, they were planted by squirrels. If you unpot them, you can look for the large nut. A location would be helpful.

3 could be Ailanthus altissimus. Hard to tell from the fuzzy photo. 2 looks strangely like rose foliage.

yes, there are a lot of squirrels here. I was told that we had hickory trees in the woods behind our house (not in our property)
