Help identify a number of plants

What are these and what do I need to do with them?
1. There are 2 things there and they’ve finished flowering? Do I cut them down now?

4 And does this flower?
these are all plants I’ve inherited with the garden. first thing I’ll do is pull out the horse weed. I’ll spread the sedum around as I have areas to keep weed free. The epimedium is new to me, i looked it up and it’s also called horny goat weed, I’ve never noticed the flowers on it, possibly very small?
The other two especially the hypericum is a bit annoying as it doesn’t flower for long, I’m wondering if I can cut it back hard now or just to a few leaves.
