Two ways are by temperature and brightness
What are some ways the stars in the photo could be grouped or classified
spectrum and temperature
Stars are classified based on their spectral characteristics, which categorizes them into spectral types (O, B, A, F, G, K, M) based on the temperature of their surface. They are also classified based on their luminosity, which categorizes them into different classes (I, II, III, IV, V) based on their brightness compared to the Sun.
Protostar formation - The Birth of a starMain sequence - When it converts hydrogen into energyPost main Sequence - When they die.
By spectral type: Stars can be classified based on their spectral characteristics, which provides information about their temperature, color, and composition. By luminosity: Stars can be categorized by their brightness, which can vary greatly based on their size and energy output. By evolutionary stage: Stars can be classified based on where they are in their life cycle, such as main sequence stars, red giants, white dwarfs, etc.
They are usually classified by their temperature.
Stars can be classified based on their temperature, which is often indicated by their color, ranging from blue (hot) to red (cool). Additionally, they can be categorized by their luminosity or brightness, which is influenced by both their size and temperature. This classification helps astronomers understand the life cycle and characteristics of different types of stars.

How are elements classified
High mass adult stars are classified as supergiants or giants, while low mass adult stars are classified as main sequence stars. This classification is based on the mass of the star and where it falls on the Hertzsprung-Russell diagram.
Stars are classified using the Hertzberg-Russell Diagram
