Go - How does one count territory in these scenarios?
For each intersection, ask yourself if it belongs to white or black.

The issue with your examples is that the games are not finished yet. You should keep playing until you can answer the question above. For now let me just try and address the top right corner.

In scenario 1, white is currently enclosing two intersections. But black will eventually capture the white stones, and all the points will go to black.

In scenario 2, white is enclosing 4 intersections (marked x below), and black cannot capture the white stones because they have two eyes. Eventually that will count as 4 points for white.

The intersections marked o will probably end as "dame" (neutral points), as neither white nor black can enclose them.
