All languages have this, at least the germanic and romantic languages do. I don't know anything about eastern languages.
Yes. Spanish in particular has a few I could name.
Qué and que are pronounced almost with infinitessimal difference, but the first one is "what" and the second one is "that" in the case of not being an "this or that" issue (e.g.remember when we went to that play?" Using "this" in that sentence would not work, so you would use "que")
Also, caro and carro. expensive and car, in order.
