Second looks like a weedy Amaranthus. Third could be Wedelia trilobata. Where are these growing geographically? And please can you take a view of the last one not taken from above and showing the stems? Are there white leaves/petals or is that just the light? Also a view of the whole plant with a scale.

Thankyou Gardengal. Once again you come to my rescue. My garden center tries to tell me that photo is salvia and I knew it could not be by the amounts of bloom in our cold weather. So thank you for giving me the name. Now I can go look for it.

Also pls check this plant carefully as this Hoya (compacta, as said above) can get mealy bugs easily inside all its nooks & crannies, partly why I stopped growing this particular Hoya, even tho' I really like the look of it. There is also a Hoya forum where you can read further on this plant & recommended care of Hoyas. https://www.houzz.com/discussions/hoyas

FWIW, the surface and pattern on the leaves is unlike any snake plant I've ever seen - and I have several varieties. The photos are sort blurry, so that might be a bit hard to make out.
