The smallest atomic number and atomic weight for a lanthanide is lanthanum itself, element 57. The smallest atomic size is lutecium element 71; the lanthanides steadily decrease in atomic radius through the series, and the smallest is the last of them.
The chemical element with atomic number 57 is Lanthanum (La). It is a Lanthanide, as it is what the rest of the Lanthanides are based on. It has 57 electrons in 6 shells. It is naturally occuring and non-radioactive.
Promethium (Pm) is the only synthetic element in the lanthanide series. It is not found naturally on Earth and is typically produced in nuclear reactors.

No, germanium is not a rare earth element. It is a metalloid in group 14 of the periodic table, along with carbon, silicon, and tin. Rare earth elements are a group of elements found in the lanthanide series of the periodic table.
The element with 62 protons is samarium, with the chemical symbol Sm. It belongs to the lanthanide series of the periodic table.
Thulium is an lanthanide element with atomic number 69.
