how to get off from terminal 2 to causeway bay and how to get to the airport terminal 1? thank you.

Causeway Bay covers a large area. In general, you can follow the signs to reach Ground Transportation Center to take the airport shuttle bus A11 to reach Sugar Street, Yee Wo Street Station. The Sugar Street is just in the Causeway Bay area.

Automated People Mover will transit passengers from T2 to T1.
