Yes. There are eight Noble Persons (aṭṭha purisa puggalā), two at each stage of Nibbana.
– Thus, both Sotapanna and Sotapanna Anugami are Noble Persons at the Sotapanna stage.
Sometimes I specifically write Sotapanna Anugami to emphasize that it is the first Noble Person. But both uses should be OK.
Thanks for bringing it up for clarification.
