Hm, let's see here, then. I'm not super-strong the lore, so someone like Sounsyy could probably run circles around me, but I'll give it my best.
Gladiators are, from how they're portrayed in game, show-fighters who fight on the Bloodsands of Ul'dah. Fighting for riches, glory, or just for the thrill of the fight. Of course, you're not limited to this and can just visit the guild to work on your sword and board skills, such as Chachan does.
Paladins come in two forms. The first and most high profile is the Sultansworn, basically the personal knights of the Sultana. They serve her first and foremost, even above other issues, though Nanamo does seem to have a sympathetic ear for the plight of her people. Those Paladins who are not bound to the Sultana and seek to serve elsewhere or Eorzea in general are known as Free Paladins.
Mechanically, GLD/PLD is a cooldown-based tanking class. You won't have as much health as a MRD/WAR, but you will have so many more cooldowns you can burn to keep yourself alive. Regardless, the class has the ever-useful AoE enmity move Flash and the aggro-grabbing Provoke that you'll want no matter which tanking class you play.
Now onto the one I know a bit less about...
Marauders, on the other hand, are basically a more structured and legal version of Eorzean pirates, since the axe is the common pirate weapon there. They're known for their brute force and their intimidating prowess.
Warriors are those who have learned to tap into (and hopefully control!) their Inner Beast. This skill is mainly known and passed down through a tribe from (quick Google search...) Ablathania's Spine. Should you seek to learn the ways of the Warriors, you must needs seek one of them down. Or be a member of the tribe yourself...
Mechanically, MRD/WAR is a... management-based tanking class, I suppose? Once you get into Warrior, you use Defiance and build up stacks of Wrath that you then spend on abilities. These abilities include bolstering your defense, removing the damage penalty from your Defiance stance, and other tricks. Rather than using defensive cooldowns, you're a big wall of meat who uses abilities like Bloodlust and Mercy Stroke to supplement the healing being thrown your way.
