Hello and welcome,
These seem like vandalism, not actual art, which would make them ineligible. They appear to have been added by someone who didn’t have permission to paint them, so they were put up illegally. There is clarification on this:
Brazil is quite known to have a good deal of vandalism as Wayspots, and from time to time, these do get removed for not meeting criteria by staff. So, even if you do see Wayspots for these still around, don’t expect them to still meet criteria, as that changes from time to time.
You may want to check out the Wayspot Criteria to know what may or may not be eligible. You may also want to review the Criteria Clarification Collection, which has more info on several different categories.
