Around your house your work is cut out for you. You have to remove the dirt away from the house plus a good overhang or roof eave as they call it also is a big plus in keepkeeping water away.
As far as that front garage wall, I can't see the eave up above but for the time being flashing of some sort is the simplest option. AtYou can also stack some bricks there too, it will go more with the stucco you have.
At least it looks like you have a positive slope with respect to that wall.
