The first could also be one of the spring bulbs as well. As suggested, check for an onion or garlic smell. I'm not 100% sure the second is angelica. It could be but it could be something else too. There are plants that do look similar - even ones that are very poisonous. Do not eat or taste unless a 100% ID is made by an expert. I'm not trying to scare, I just want you to be safe. Can you get a better view of the leaves of the 3rd plant? FataMorgana

I know this is late, but I was on eBay and saw an O. Kleiniae. I saw the pic and I thought I know I've seen that before. It's not right on, but close. Then I saw O. imbricata which has some similarities to your cactus also. Idk I thought I would just let you know:). Guess we gotta wait till it grows more and blooms.

Try comparing to Veronica persica for #3. I see you have some dandelion in #2, I would expect them to be bunny edible. If you have dandelion, chickweed, veronica, etc., it is obvious that you have broadleaf weeds and so I would look for plantain (Plantago spp.). Probably another one you can feed the bunnies.

One of the Thread-Waisted Wasps. The normal in-life antennae posture is straight or slightly curved. You describe the wasp as trapped; perhaps it is also dead and the curled antennae are a random result of that. https://bugguide.net/node/view/135 ^size (length) described here as up to 30mm (1.25")
