Planck units of time and space are thought to be the smallest measurement units that still have a "practical" use (in the realm of quantum physics), but I could say "well then, I nominate the shekelmeter to be equal to 1/1,000,000 Planck length" and that would be the smallest measurement unit, it's jsut that no one would use it and it would have no application
The elementary charge e is thought to be the smallest charge possible in nature, but quarks have charges that can either be 2/3 or -1/3 e, which is how a proton gets a charge of 1; however it's not been demonstrated that free quarks can exist in nature, or can be made stable for a significant amount of time in particle accelerators
