Birds of North America online notes that the immature birds remain with their parents not only for their first year but for several years. So the birds that winter here are likely parents and several generations of their offspring. They will likely be leaving soon to fly back to their breeding territory.
The goose in top pic stands out as an adult bird, showing the white forehead and the dark stripes on the belly and lower breast area. The 2 geese in the middle pic have more limited white on forehead and ventral bars that are not as dark or wide as on the adult birds. The 2 geese in the back in the bottom pic appear to be first winter birds, with limited white on forehead and just developing black ventral bars while the bird in the front is an adult. SeEtta
