Ophiopogon japonicus 'Nana' or similar.

Some sort of Stachys.

First, where do you live? We need to know your climate and therefore if any of these will grow there. If they won't, maybe people here can suggest something comparable in color and form that will do OK in your climate. Image #1: Are you talking about the Dwarf Alberta Spruce? or what looks like a Dogwood? Image #1: small yellow shrubs -- too far away to tell for sure. Could be Goldmound Spirea, could be the new growth on Nandina 'Firepower'. Image #2: Reddish shrub looks like Japanese maple - Acer palmatum dissectum (weeping type). Greenish yellow shrubs -- too far away to tell. Perhaps Spirea, perhaps Euonymus. Or something else entirely. Image #3: too far away to tell for sure. Could be Firepower again (new growth), or Euonymus Emerald 'n' Gold, or Golden Barberry or something else.

The cactus might be an echinopsis. Does it have big, showy flowers? The brown part is probably corking after some old damage (sunburn? frost? mites?). As long as it is not spreading quickly it shouldn't be a problem. The last one is definitely an Aloe, but probably not A. vera. I don't know which one, though. These could all use more light. If you are moving them into full sun, be careful to do it gradually so they don't sunburn.
