Do these weep holes look like a problem?

[redhexagonal]

3m span upvc patio doors, cavity wall built 2015, there are 3 (maybe 4?) what I think are weep holes or gaps in the mortar at least. There is one brick which is randomly sticking out of the wall too with a bit of a hole next to it, not sure if its intentional. Does it look like weep holes are correctly installed for this span, and if not how can I test that or get them fixed?

Looks like weep holes. the loose brick may have been a scaffold point

Do the weep holes need any attention? That brick is sticking out but is firmly mortared in place

It will be acting a a weep hole even if not intended, I would leave it there if there is no sign of damp on the inside.
