A normal CO2 laser will do all those materials, most of them engraving AND cutting.
Glass only engraving. And beware of plastics: some might produce hazardous smoke or corrode your laser. Don't do PolyCarbonate, for instance. Keep it with Acrylic, preferably Cast-Acrylic.
BTW: CO2 is also exelent for engraving on anodized Aluminum.
