The first one is definitely a peony. The third looks like a Shasta Daisy. The other 2 look familiar. But..

It looks like a picture winged fly. I see them around, don't think they cause any trouble.

We have a used furniture store in my smallish town. They buy out of estates in local higher-end communities. I have gotten several great deals there (with free delivery!). You do have to kiss a lot of frogs. See if you can find a couple of those kinds of places in your area, make friends with the owners, and let them know what you are willing to wait for. Visit frequently. Good luck! And, coincidentally, one of my buys was also a Palecek chair. My upholster recovered for $35!

Great. I hope they eat all the aphids hiding under the giant nicotiana leaves
