I'm not much of a pro in luring but let me attempt to identify these lures for you.

I think SGPU can provide a more detailed explanation on how to work them.
The first one is a popper, it's used to target near surface fishes that are attracted by the sound, vibration and splashes it creates when you twitch it. You can get baramundi, barracuda, queenfish and other types of surface predators.
The second one is a stickbait with propellor and is a type of topwater lure like the popper. The lure head will turn sideways alternately as you twitch it and the propellor aid as producing sound and vibration to attract fish.
The third one is a minnow, a type of crankbait. The lure waggles as you retrieve it and typical dives 1-2 metres below water surface. It can be used to target for fishes near surface and also bottom fishes if you're fishing in shallow places.
The fourth one is also a type of crankbait. It has a bigger lip so it probably can dive a litte deeper than the minnow, targeting more on bottom fishes like groupers.
All of the above lures can work on snakeheads and peacock bass if you're into freshwater fishing.
Take care of the hooks and remember to wash them after use, especially if you fish in saltwater. They can rust pretty fast depending on the make and quality of the trebles.
