You need to go to a better site. Someplace that's going to ask you whether the needles are flat or round, how their attached, etc.

Can you suggest a site?

3 different plants, the last one (#4) being dead for all intents and purposes. And all are needled evergreens or conifers so posting in the Conifers forum - with better and more detailed photos - or in the Name That Plant forum should generate better responses.

Use google lens.

I very much doubt that google lens will be any use. Identifying conifers, even with good pictures, is a skilled job.

eta doubts confirmed. Google lens produces a bunch of random conifers. Plus Lonicera nitida, Cotoneaster horizontalis etc. ....

I had a similar situation with my Helleri Holly dwarf bushes. I added more Miracle Grow potting mix to the soil underneath the shrubs; and in a short time they came back to life! Now I faithfully add Miracle Grow yearly to them and make sure they get extra water during dry spells.
