None, Maine was the only state to join the union in 1820.
Both Maine and Missouri were in the same position. They could not gain entrance to the union without the other. At the time, whenever a free state entered the union, a slave state had to enter also. So admitting Maine, meant admitting Missouri.
When Missouri was admitted to the Union on August 10, 1821, it was part of the Missouri Compromise, which also included the admission of Maine as a free state. Maine entered the Union shortly before Missouri, on March 15, 1820, to maintain the balance between free and slave states. Therefore, Maine is the other state that came in around the same time as Missouri.
Missouri. I bet many people didn't know that Missouri was a state for both the union and confederacy at the same time during the civil war

No. A civil union bill has never been introduced in the Missouri legislature.
No, Missouri does not.
The whole issue that drove the Missouri Compromise was the admission of Maine to the Union as a 'free' state. In the deal that Henry Clay cobbled together in Feb-Mar 1820, Maine would be admitted as a 'free' state and Missouri as a 'slave' state thus maintaining a balance. At about the same time (May 1820) Congress made foreign slave trading an act of piracy.
principally in admitting Missouri, a slave state, and Maine, a free state, into the Union at the same time, and in regulating slavery in the former Louisiana Territory
Maine had to agree to enter the Union at the same time as Missouri to maintain the balance between free and slave states. The admission of Missouri as a slave state threatened to disrupt this balance, which was crucial for preserving peace between the North and South. By allowing Maine to enter as a free state simultaneously, Congress aimed to ensure that the number of free and slave states remained equal, thus averting potential conflict over the issue of slavery. This compromise was part of the Missouri Compromise of 1820.

Minnesota became a state the same way other states became states. The leaders of the Minnesota Territory petitioned the US Congress to join the union. After verifying that Minnesota had a viable constitution, large enough population, and a functional government, the US congress passed a law admitting Minnesota as a state. That happened on May 11, 1858.
