Back in Pokémon Bank, after you select Pokémon Alpha Sapphire and choose "Use this Game", your PC Boxes in Pokémon Alpha Sapphire will be displayed in the touch screen, and your Pokémon Bank boxes will be displayed in the upper screen. Use the control pad or circle pad (the stylus cannot be used in Pokémon Bank) to move the desired pokémon from Boxes in the the touch screen to Boxes in the upper screen.
You can press START to switch between a red cursor, which shows you several options when you select a pokémon with it; a blue cursor, which picks up one pokémon at a time without showing any options; and a green cursor, which allows you to select multiple pokémon at a time.
When you are done moving your pokémon from Pokémon Alpha Sapphire to Pokémon Bank boxes, press the X button to save your changes and return to the title screen.
