How do I change the position of a port on my component?

Geometry Elements - Components

You may change the position of a Component port by selecting the desired port and dragging it to a new location. A blue triangle appears when your mouse moves over a possible location for the component port.

You may select multiple ports and move all of them at the same time but be aware that if you move multiple ports, their relative positives remain the same when they are moved to a new position.
