Is the word "stray" used commonly? Is it same with "lost"?

Yes, they have similar meanings. Synonyms for "stray" include "wandering" or "random." It usually refers to people (or animals like cats and dogs) who don't have a fixed home and wander around on their own, like the "adventurers" mentioned in this video. Ex: The stray dog was very thin and dirty. Ex: I helped a stray tourist who had gotten lost.
