Are The first four elements in the alkali metal family have the same number of electron orbits?

No, the first four elements in the alkali metal family—lithium (Li), sodium (Na), potassium (K), and rubidium (Rb)—do not have the same number of electron orbits. Lithium has 2 electron orbits, sodium has 3, potassium has 4, and rubidium has 5. As you move down the group, each subsequent element has an additional electron orbit, leading to increased atomic size and different physical properties.
