Interchangeable means that you can swap out similar or identical components with different objects. For instance, “This telescope’s eyepiece is interchangeable with these binoculars lenses”

It might be tricky in some cases where they could theoretically be used in the same context, for instance “the table cloths are changeable/interchangeable”, where the sentence can either mean “they can be changed (to be washed)” or “they can be interchanged (to make a different style/look)” making the differences extremely small.

A: changeable means that it is likely to change throughout the day. For example: "it was sunny this morning and now it's pouring rain. The weather is really changeable today." Also: " they are predicting that it will snow this evening even though it's sunny and warm right now." "I'm not surprised, the weather has been really changeable recently."

unpredictable means that the weather cannot be anticipated. For example: " I had planned to have a barbecue today because the forecast said it would be clear skies but it's raining. It's a shame the weather is so unpredictable"

The meaning is quite similar. the main difference is that changeable weather can be predicted as it just means that it will change but unpredictable means that it can't be predicted for whatever reason. This reason could be that it is too changeable or something else like the weather report is inaccurate or their is a freak occurrence.
