Using the numbers from the top link, where you put the red numbers:

1 & 4 - look like Sedum, probably 'autumn joy'
3 - looks like Stachys (lambs ear)
2 - looks like Muscari (grape hyacinth)

About the sedum, those old stems should break right off, use a downward twisting motion instead of pulling straight away.

Also, forgot to say, you can find your zone here:

That's great thank you very much. Is now a good time to break the stems off the sedums to allow new growth?

No thoughts on plant #5?

Yes, I like to leave the old stems of the sedum up, as you did, so I know where the plants are. I also think they help 'catch' leaves and snow. Now that you can see them well, removing the old stems will make the plants look fresh and 'clean' although the new growth would be unaffected either way. If you accidentally pull a chunk with roots & new stem, just bury it back to the level it was or slightly deeper. Unless it completely goes bone dry, it won't mind, probably won't even stutter.

#5 - hope somebody else can help. My only guess is squill and I don't think that's right, leaves are too broad, too many buds on the stems. Looks like they'll be extremely pretty, whatever they are!

Perhaps Albuca nelsonii for #5. You should wait till it grows more & the buds open-maybe repost a pic. Are the buds striped at all?

Check out link below for a pic of one a bit further along than yours.

Thank you. I will post another pic after it blooms.

I think no 5 is Hyacinthoides hispanica - Spanish bluebells. This would fit in with the likely zone and the common nature of the other plants pictured. Albuca is a S. African half hardy native which is unlikely to feature in a garden in Ohio.
