Yes, you'll have to see ALIEN first; it sets everything for Aliens; you will appreciate Aliens more if you do. Please try to see the director's cut with footage not shown in theaters because of the present 70's generation. The first film is a haunted house feature in space while the second one is more action oriented with strong monster film elements (chase sequences). Alien 3 appears to be inspired by the original film moreso than the others. Alien Resurrection is the one more on science fiction with monster elements.
