How can I achieve an angled ripple like in image 1? Thanks!

You could create the ripple effect on a simple 2D plane and then rotate the plane in 3D space to be at an angle. However, note that that would still just be a 2 dimensional effect and won't have the 'depth' of the samples you provided.
If you want to create something like the examples you had you will need to use a 3D program (e.g. Blender) or plugins for After Effects such as Element 3D - and then import a 3D model of a ripple.
Hope that helps!
