Yes, Calcium and Barium are both Alkaline Earth Metals.
The elements Ba (Barium) and Ca (Calcium) belong to the same group on the periodic table, as they both belong to Group 2 (alkaline earth metals). They do not belong to the same period, as Barium is in period 6 and Calcium is in period 4.
Chlorine is in the same group as fluorine, as they both belong to Group 17 (halogens) of the periodic table. Meanwhile, chlorine is in the same period as sulfur, as they both are on the third period of the periodic table.
a 'family' of elements or also called a group
Two elements that belong to the same group are sodium (Na) and potassium (K), which both belong to Group 1 (also known as the alkali metals) on the periodic table.
The element in the same group as Al is boron (B). They both belong to Group 13 in the periodic table.

Carbon (C) is in the same group as Silicon (Si) because they both belong to Group 14 of the periodic table.
Sodium (Na) and potassium (K) belong to the same group on the periodic table, Group 1, which is the alkali metal group. They have similar properties due to being in the same group, but are located in different periods - Na is in period 3 and K is in period 4.
Elements that have many similar properties belong to the same group on the periodic table. Each group shares similar chemical characteristics due to their same outer electron configuration.
Mercury belongs to same group as gold. Both belong to period-6.
Elements with the same number of valence electrons are in the same group (or vertical column).
According to Chemists, the elements of sodium and chlorine belong to the same atomic family as well as carbon and lead.
