For Part E, have you drawn a diagram yet? You should google the definition of a bearing and how to obtain it in terms of an angle. You then have an angle, a hypotenuse and an opposite:

Part F is a standard Force diagram along an inclined surface:

You are calculating the component of the force parallel to (i.e. along) the surface

Part G, H and I seem similar to above. For example in Part H you literally model the hill as a triangle and you have a slope that you walk up along. For Part I, you can see the force diagrams here:

For Part J, you need to decompose, not forces, but velocities in a similar manner as before.
