These Magicite are given to you by Ramuh in Zozo. These are impossible to miss, given that you have to talk to Ramuh to move the plot along.
They can both be found at bottom of a pit in the Magitech Factory. To advance the plot, you must fight and defeat them. Once beaten, they yield their Magicite to you. You only need to pick up Shiva to continue with the game.
Shortly before leaving the Magitech Factory, all of these Espers give their Magicite to you. You can't really avoid taking them.
These can both be found in the Auction house in Jidoor. You just need to buy them.
This Magicite can be bought from a traveling salesman in Tzen for 3000 GP in the World of Balance or 10 GP in the World of Ruin. You learn of this man in either the WoB, or the WoR from one of the old men near the dock area. The man is walking/hiding behind some trees in the upper-right corner of the town, all the way in the back.
After getting the airship in the World of Ruin, return to Cid's Island, and you will find this Magicite on the beach.
After defeating Phunbaba in Mobliz for the first time, a kid will give this to you if you talk to him.
Go to Narche and go back to where you defended him before. If you manage to defeat him, the Magicite is yours.
This can be found in Umaro's Cave in Narshe, simply search the skull there, and it's yours.
Defeat Chadarnook in Owzer's house in Jidoor, and collect it from Owzer's bookshelf.
Go to Doma in the World of Ruin and do the entire Cyan quest. At the end of the quest, it will be sitting on the throne in the throne room.
Go to the star shaped mountain range north of Tzen and land in the middle. Complete the dungeon, and Locke will give you this Magicite.
Find Doom Gaze while flying around in the airship. Defeat him, and Bahamut is yours. Be sure not to use the Vanish/X-Zone trick, or you will not receive Bahamut. However, Vanish/Doom will work every time.
Defeat all 8 dragons, and this Magicite will suddenly be given to you.
Go to Figaro Castle, in the World of Ruin, and try to move the castle somewhere else. It will get stuck under the sand, and you can enter a new cave via a hole in the prison level. Go through the cave and enter the Ancient Castle there. Walk straight ahead and talk to the statue of Odin. It will yield the Odin Magicite. To get the Raiden, stand on the right throne, walk five steps down and press the A button. A secret passageway will open. Go down it, and you will find a statue of a girl. Talk to it, and the Odin Magicite will become the Raiden Magicite. Once you transform Odin, it is lost; fortunately, the only spell it teaches is Meteor, and you can also learn that more quickly from Crusader, so don't worry about it.
In the World of Ruin, go to the Narshe Weapon Shop with Locke, and he will unlock the door. Inside, a man will ask you if you would rather have the sword Ragnarok or the Magicite Ragnarok. Choose the Magicite, and it will be yours.
Leviathan is only in the GBA version of the game. In the World of Ruin, talk to the man near the entrance of South Figaro. He tells you about a creature he saw in the ocean. Afterward, go to Nikeah and ride the ferry. During the trip, Leviathan will attack. Defeat him to gain his magicite.
Gilgamesh is only in the GBA version of the game. In the World of Ruin, buy Excalipoor in the Jidoor Auction House for 500,000 Gil. Then bet it in the Dragon's Neck Colosseum. One of your characters will have to fight an Onion Dasher. After the match, Gilgamesh shows up and challenges your party for Excalipoor. Defeat him, and you get his magicite and a Merit Award.
Cactuar is only in the GBA version of the game. In the World of Ruin, defeat ten Cactuars in the desert near Maranda. Eventually, you'll be attacked by a Gigantuar. Defeat him to get the Cactuar magicite.
Diabolos is only in the GBA version of the game. Defeat Kaiser Dragon in the Dragon's Den for it.
