The elements in the same families (columns) are the most similar.
Chlorine and Bromine have similar properties. You can tell because they are in the same vertical column in the periodic table.
These elements have more or less similar chemical properties.
You can tell by the location, and the fact that they are both in the same column. Elements in the same column (or group) have similar properties.

Elements in a group generally have similar chemical properties because all the elements in that group have the same number of valence electrons, so Ga would be more similar to Al.
They can, however in Groups the properties are much more similar.
No, but elements in the same vertical columns have similar properties.
