It depends on the situation. A "companion" is someone or even an animal who you spend a lot of time and travel with. A "companion" can be both a partner or a friend. Most people consider companions their friends. However, definition-wise, a companion is considered more of a partner than a friend. Ex: Her dog is her best friend and travel companion. Ex: His sister has been his companion his entire life.
