I am interested mostly in the diffusion coefficients of K and Ca in Fe and Ti-oxides, but also for the interdiffusion coefficients of Fe and Ti. Any help with resources or ways to calculate them is very much appreciated.
For a start take a look at:

You'll find some basic description and resources.
Thank you, Dr. Rawle! I will take a look at your lecture. Can you recommend a database with diffusion coefficients that you use in your practice? Thank you.
Look at Slide 21 to get some ball-park figures and isolate the different diffusion mechanisms that may or may operate in your case and at the appropriate temperatures. Before trying to get every number out, take a look at:

You have 4 elements in 3 systems (minimum - the word 'mixed' is used which implies infinite possibilities) which is a minimum of 12 numbers. So the big picture is often useful.- try and grasp this first.
