I am in Oregon in Zone 8 and I pruned my roses this weekend. Usually we prune around presidents day, or when the forsythia blooms. I also took advantage of the nice weather. Your roses look just fine. You probably could have cut off some of the smaller branches (smaller than a pencil) but we learn from experience, and you really can't hurt them. The height looks fine. Now you can spray them with Lime/sulpher and horticultural oil if you want. I mix the lime/sulfer and oil at dormant strength (on the bottle) and spray within the next week if you can. You want to spray before leaves start to form, because the dormant spray will kill new growth. The dormant spray kills fungus spores and the oil smothers insect eggs that may overwinter. If you don't get around to spraying the dormant spray, wait until they start leafing out and start spraying for fungus. I start in late March. Good luck Kathy

Temperatures in the mid-20s likely will zap the new growth on your hydrangea, especially if it's a macrophylla-type hydrangea. If it is a macrophylla-type that's been "forced", I would dig it up and store it in the garage overnight. In fact, I'd put it back in a pot for easy transport to and from the garage until you've passed the last threat-of-frost date for your area to give yourself the best chances for getting blooms this year.

They look normal to me. My plants up here in New Jersey just broke dormancy - at least some did. Considering our unusually wet winter it wouldn't be a surprise if the rest were dead. They've been given a couple more weeks to get there act together. "Do you hear me out there"! "This is your final warning"!

If you google lychee seedling and click on images, this seems to look pretty normal. Perhaps some the people who posted the photos also discussed their methods. Seedlings are tricky to water correctly, I'm always second-guessing myself.
