Integrated mixer/full-length nacelle: PW6000 or IAE V2500. The 2500 is a bigger engine, but you can look at the plane length to know which one it is (318->PW, 319/20/21->2500).
Short duct, no cone in exhaust: CFM56-5 (the 5B is slightly longer, but it's hard to see)
Big fan and BP duct, cone in exhaust: PW1000G or LEAP. From the front, the LEAP has two bulges at the 4 o-clock position, from other angles they're tougher to tell apart.
