We have a stack made by C2960X-48FPD-L, C2960X-48FPS-L and C2960X-24PS-L. The first SW can have SFP+ but the others don't. In existing architecture the first one has a 1000BaseSX SFP maybe for compatible with the others. Can i put a 10GBaseSX SFP at the first one? And maybe change the speed to 1G ?

- Speed of fiber SFP can never be changed also look into : https://tmgmatrix.cisco.com/

No that SFP works same speed, you can not have 1 side less and other side higher one to work.
more information device SFP compatability matrix matrix link provided by @marce1000
For better smooth working, suggest to use 1GB SFP both the side.

Thanks for the answers but was not in that line of thinking. I know i need the same speed in both of sides.
I was asking about the stack, could i plug the 10G instead of 1G. My coworker has pluged there some time ago an 1G SFP, so the question is: is ok to plug a 10G SFP in the master stack switch once it is compatible or i can not because the other 2 switches of stack are not compatible with 10G SFPs?
I never worked with switches in stack so need to know before do something wrong if i can change it or not.

Its all depends on the model and what module you installed.
Stacking - virtual or flex stacking ? Look at the documentation of that product will help you based on the model.
