Yes there are Cholov Yisroael versions of things that are at least similar (if not exactly alike) to everything you mentioned.
The kosher version of M&M’s are even called that name by those who eat them, even though the name on the package is something named from a kosher company and is not made by the same company that makes M&M’s, but they taste the same 🙂
Now something like, Reeses Peanut Butter cups and Butter Finger bars, I have not seen in Cholov Yisroael, recently, but most things are available in Cholov Yisroael versions.
