Here's a little bit of Pick-n-choose to get going. You have conventional caterpillars that follow in a single line, or Squad systems that let them follow.... SORTA... behind you but appear a bit more realistic in na- na-- DID I SAY IT LOOKED REALISTIC? XD

Enhanced Squad Movement
DerVVulfman (December 25, 2017)
Caterpillar, or party-following systems, have been around in RPGMaker games for years. Yet most follow the same basic single-file design. Not so with Near Fantastica's Squad Movement system, a system which allows the player to deliver a couple of limited commands. Now revised, this rendition of Near Fantastica's Squad Movement comes with a detailed configuration system, and a host of script calls that can give the game developer a strong sense of power over the player's visible party.
KA-terpillar + Settings
kyonides (May 20, 2014)
This plug and play script lets you see the other 3 party members on screen like other scripts do but also lets you change the current party formation by shifting the first member to the last position or the last one to the first position or it shifts them semi-randomly for you. You can check its simple menu to change the settings at any time, it even includes dummy characters so you can check out what are the changes that you want to apply to your team.

Train Actor / Caterpillar
by fukuyama (2004)
EDIT by Blizzard (2005)
This is an edit of possibly the first and best known caterpillar system for RMXP. It will let your party members "follow" the main character on the map.
Trickster's Caterpillar System

This is a caterpillar system nothing special. This code is based on Fukuyama's version only better.
