If you actually know what you are talking about (you have had an education), you can say and do things that are correct and true.
Yes! "She is with me and John." You can test it out by using the sentence with just one of the persons at a time. For instance, "She is with me." is correct. Also, "She is with John." is correct. Therefore "She is with me and John" is also correct. (However it might sound more natural to say "She is with John and me")
"In" is probably more correct, unless the name of the event is a place-name. "I participated IN the Daytona 500", or "I raced AT Daytona."
The correct spelling is "Paralympian" (athlete who has participated in the Paralympic Games).
"People" is the usual plural of "person." However, you can say "persons" to emphasize the individuals. So... 3,908,000 live in Guadalajara. But I spoke to only three persons that night: the cab driver, the wino, and the ballerina. In the second example you could also say "people." Special circumstance: The police keep files on missing persons (not missing people).
No, it is correct to say 1 person.
