I have four types of input images, and I want to know that can I set different learning rates for each types?

If it is possible, let me know how to implement it and some keywords about it

You could use different optimizers for each input type and call it w.r.t to the currently used input.
The use case won’t work if you are working with a batch of images containing multiple types of inputs and you would have to define a “default” optimizer.
