They can take full sun, but do better with a bit of shade. Two-gallon pots are a common size; you will also find 5-gallon pots. You are looking for container plants that are 2 to 3 years old (you can also buy bare-root blueberry shrubs). They won’t necessarily do better planted together but by grouping them you are ensuring they have the same soil conditions, and it makes watering both easier and more uniform. When planting, space the shrubs 4 to 6 feet apart (If you go with bare roots, plant them in early spring while plants are still dormant.)
