From simple google searches you can find that Yoda's midi count was 18,000 per cell, Obi-wan's was 15,000, Palpatine's is said to be higher that Yoda's around 18,500-19,000, and the highest known was Anakin Skywalker's at 20,000 midis per cell.
The highest known midi-chlorian count—over 20,000 per cell—belonged to the Jedi Anakin Skywalker, who was believed to have been conceived by the midi-chlorians.
The Jedi however also have three outliers in that of Luke, Leia, and Cade Skywalker (23000/23000/21000 midi-chlorians respectively) all of which were children/descendants of Anakin Skywalker (the chosen one) and so genetically predisposed to having abnormally-high midi-chlorian counts for Jedi.
Obi-Wan Kenobi's Midi-chlorian count is around 13,000, Yoda's clocks in at 17,700, and Darth Sidious is estimated to be about 20,000. Anakin Skywalker is said to have had the largest Midi-chlorian count in Jedi history, which is around 28,000 to 30,000, with George Lucas insinuating it could be as high as 40,000.
That said, both Yoda and Yaddle have a high midi-chlorian count in their blood. Yoda's m-count was roughly 18000, while Yaddle's was closer to 12000. It is reasonable to assume that whatever species they are a part of, it is a deeply Force-sensitive one.
Obi-Wan Kenobi is the most famous example of a Jedi with a low midichlorian count, but who ultimately became a very powerful Jedi simply through hard work.
In Legends, Obi-Wan's midichlorian count was around 15,000. Yoda's was around 18,000, and Palpatine's is estimated to be just higher than Yoda's so let's say it's between 18,500 and 19,000.
No he did not. The midichlorian measurement is taken as density/concentration instead of as a total amount. As darth vader he still had the same density of midichlorians.
The existence of midi-chlorians was known to both the Jedi and the Sith. The Jedi Order utilized the scientific procedure of blood testing to estimate the number of midi-chlorians within prospective initiates.
Over 20,000. Not even Master Yoda has a midichlorian count that high.”
Master Yoda has risen above all others to claim the top spot as the most powerful Jedi of all time and the true chosen one according to IGN's audience. He won pretty handily as well, as he was victorious in 89,756 of his 95,243 battles and had a win percentage of 94.2%.
Anakin Skywalker is the son of Shmi Skywalker, born without a father through the Force. He is the secret husband of Padmé Amidala, the father of Luke Skywalker and Leia Organa, the father-in-law of Han Solo, and the maternal grandfather of Ben Solo.

During his time as Darth Vader, the powerful Force-user continued to hunt down Jedi, devoting himself to the Order's extinction until he became aware of his son's existence.
There are a lot of hints given throughout the Star Wars franchise that Padmé Amidala was in fact Force sensitive. It is clear that the young queen and later senator from Naboo was not strong in the Force or trained in the ways of the Jedi, but she very likely still had some low-level sensitivity.
Anakin Skywalker was a living vergence in the Force, and as Darth Vader he was a force to be reckoned with. But was he more powerful than Luke? As powerful as Darth Vader may be in Star Wars, he pales in comparison to his son, Luke Skywalker.
During his confrontation with Obi-Wan Kenobi on Mustafar, Anakin Skywalker was first maimed by lightsabre cuts. He lost both legs around the knees, and much of his left arm. He fell onto a slope of volcanic sand, and slid helplessly to the edge of a lava river.
In the duel, Anakin lost both of his legs, his one remaining organic arm, and suffered (possibly up to) fourth-degree burns across what was left of his body that were severe enough to damage his internal organs.
Both in the books and the movies. After the events of Return of the Jedi, it is intimated that he is possibly the most powerful light side user of the force during that time period. It's not a question. He is infinitely more powerful than Rey.
In a new excerpt, it's revealed that the names of Rey's parents are Dathan and Miramir. Dathan is the dad and Miramir the mother, if you were wondering; it's not always clear with these names from a long time ago in a galaxy far, far away.
Darth Jar Jar, known to most as Jar Jar Binks, was a Gungan Sith Lord. He survived the Battle of Naboo and became a Representative of Naboo, when he helped to give Darth Sidious emergency powers. After the fall of the Galactic Empire, he forced a small alien named Snoke under his evil wing.
Ahsoka Tano, a Togruta female, was the Padawan learner to Anakin Skywalker and a hero of the Clone Wars. Alongside Anakin, she grew from headstrong student into a mature leader. But her destiny laid along a different path than the Jedi.
The powerful dark side-wielder Kylo Ren was adept at the mind probe and used it to great effect, with his use of the ability being strong enough to exert physical force on a target with enough effort, either to pinning them down or to hold them up.
While Jedi could create Force lightning, like Sith, they choose not to use that power due to its association with the dark side and immoral nature. Despite being equally as strong in the Force, one innately Sith ability that Jedi in the Star Wars franchise do not wield is Force lightning.
Jedi Masters typically have around 15,000 midi-chlorians per cell, and this is generally accepted as the max midi-chlorian level. Examples of such masters would be Count Dooku, who is estimated to have 14,000, and Mace Windu, who is estimated to have 16,000.
