Probably between 300-400 on average and depends on how much you work out.
I am (just graduated) a high school lineman, didn't work out much, benched 330. So you imagine someone who works out that is big in size would bench around 400 in high school.
same as pro football

Yes.
Good question, but I don't think you can. I suppose you can search up "High School Football Rules" on Google, But you may, or may not be able to find them, Also rules can be different in various locations so keep that in mind.
In college football the kickoff is made from the kicking team's 30-yard line.In the NFL, it's the 35. In high school, it's the 40.
Anyone you choose! - Most coaches would have you on the line
Offensive or Defensive line.
