12x12=144
For a 12x12x2-inch cake pan, you typically need about 1.5 to 2 standard cake mixes, depending on the brand and recipe. A standard cake mix usually yields enough batter for a 9x13-inch pan, which is smaller than your 12x12 pan. To ensure you have enough batter, consider using two mixes or adjusting the recipe accordingly.

that depends on how many slices you want.

Normally 12-16 slices but it depends on the sise of the cake.
A 10-inch round cake typically yields about 12 to 16 slices when sliced thinly. The exact number can vary based on the thickness of the slices and the specific cake's density. If the slices are particularly thin, you might be able to get closer to 16 slices, while thicker slices might yield around 12. Ultimately, it's up to personal preference on slice size.
That's difficult to answer because a sponge cake is very light and a pound cake is very dense, so you really need to indicate the size of the cake to get a better answer.
It depends how big you want the slices.
A 9x13" cake will feed about 45 people (assuming that the cake has two layers, each layer is about 2" in height, and the slices are 1.5x2" in size).
