Distribution of Current in Kirchoff's Junction Law
It's just an example. You may imagine a different case or example if you want.

Any of those current may be inflowing or outflowing, as long as total current inflowing equals total current outflowing.

Also, currents inflow or outflow depending of the conditions in other nodes. If there is a negative voltage difference with respect to another node and an impedance low enough (i.e., finite) to it, then there will be an inflow of current.
