No. They are 9–12 grades.
Yes, like all US States, Oklahoma has high schools. However, most will not cover grades 5-12. Most cover grades 9-12.
Because most High Schools (in the US) consist of 9th-12th grades. 9th = Freshmen, 10th = Sophmore, 11th = Junior, and 12th = Senior. While some areas have 9th grade at the Jr High ans some others break High School into a 9th/10th and 11th/12th schools. The vast majority of High Schools in the US have 9th-12th grades. This is most likely to resemble a similar structure to a 4 year University and to prepare students for University.
usually it depends on the high school but if you go to a middle/high school you most likely you have to be invited by someone in high school ;)

That is the correct spelling of "junior high school" (a variation on middle schools). Junior highs may contain 7th, 8th, and 9th grades, while Middle Schools tend to have 6th, 7th, and 8th, with a standard 4-year high school for 9th to 12th.
You can repeat 12th grade. One reason you might repeat it is because you didn't get good grades. But if you get held back you will have to wait another year to graduate.
