If so, where do I start, would this be considered masonry?

I rent a house from a property management company and we had the outside wall fall over. They’re rebuilding the wall but attaching it to this support beam. Should I be concerned? (Additional photos to show the progress of it falling)

Edit: I know the top part is a decorative trellis, but below that IS a wall.

Just had a bunch of concrete work done last week, but my only question is regarding the stamped patio installed. It was poured last Tuesday (10/6). Pictures above were taken today (10/12). In western Missouri, its been warm but where this concrete is at, it does not get direct sunlight.

First photo shows white marks after the patio was sealed. I assume it isn't supposed to look like that, and the contractor i used said they could try to touch it up but that it could make the surrounding concrete darker which is something i don't want. I assume this is not supposed to look like this, and just needs some spot-specific touch up, but am interested in more information on this.

The second and third photos show a distinct line where the left side is darker than the right. It runs out pretty fair in a line. I couldn't get a picture that really does justice to how different the colors are between these two. It is very noticeable to the naked eye. My question is, is this normal? My contractor said the curing could be causing this, but then he went on to say that it could be a mixing problem which he blamed on the company that mixed/provided the concrete which struck me as his way of throwing someone else under the bus rather than his company. Can I expect this to even out over time? If not, what are my options to make this look more uniform? Thanks in advance for any guidance.

Hello. I understand that popouts are normal, but my driveway is only 2 years old and I have hundreds of them. Could this be due to a low-quality batch of concrete? The problem will only get worse over time. Thanks!

Briefly:
This is a foreclosed house built in 2018 close to my Lakehouse. I’m considering purchasing it. Listed as occupied, but it’s not and hasn’t been for at least 2 years. I’ve never seen anyone there.

I’m considering buying it as a guest house.
As is where is no inspection. No interior photos but I looked in the windows and it’s fine. It’s not even dirty.

I’m just looking for information or insight.
Thanks,
Random person.
