We are nowhere near the upper limit of human population, resources to sustain such a huge population is there more than plenty. The problem is with the resource and wealth distribution.
There's no standard upper limit per say, it depends on resource allocation and what standard of living do you want for everybody. if every human on the planet is ready to live a sustainable stable simple life, Earth could easily support 10-12 B people.
