Thanks for all the advice, it's not so much that I don't know how to fillet them, its that I'd like to know if it's possible to change them after so that I can bevel it if i want to. So that my fillet isnt so destructive. I come from a poly modeling background so that's part of why I want to know. I thought about what you said and after thinking about it I think I am starting to see what you mean. Like I said, its not so much that I don't know the order I need, it's that I am trying to see if its possible to do them in reverse, so if I do make a mistake, I can correct the issue. I am also still trying to figure out how surfaces work haha.

I am not sure how to do the thing you mentioned. blending them, I am still figuring blending and all that. Here is my file.

Anyways like always I appreciate all your help!
