Based on profile and action, #1-3 designs are finesse action lures; #4 are thumper designs.
Fish may react to all of them on certain day in certain situations or just finesse action on other days (post cold front). Though the #4 sticks wacky rigged with a jig are similar in action to the small sticks in the right, the body profiles and actions are much different on the drop.

In fact the slimmed down Sassy Shad at the top (#2) has more thump than the two thin boot-tails beneath it.

The fishy-looking lures have an excellent little tail shimmy perfect as a finesse action under a float.

The 5" Kut Tail worm when rigged on a 1/32 or 1/24 oz jig, has a whip & dart action - the most thump to the senses of any shown.
