Yes, the parent remains responsible. Until they turn 18 or are emancipated, they remain the responsibility of the parents. They determine where the child can live.

While elementary school is mandatory, high school is not. Unless the support order specifically states that the child needs to be attending high school in order for support to be paid, the answer is "NO".
In Oregon, the school district generally holds the custodial parent responsible for ensuring that their child attends school. If a child is not attending school regularly, the school district may take steps to address truancy, such as involving the custodial parent in meetings and offering support services. However, it is unlikely that the custodial parent would face legal trouble solely for their child's non-attendance, unless there is evidence of intentional neglect or failure to comply with court orders.
Go to the school, bringing necessary documents to prove you are the parent, and find out if the child is still attending school there. Even though you aren't the custodial parent, you do still have a right to know if your child is still enrolled at school. They should be required to tell you, unless there are extenuating circumstances which would prevent them from doing so.

That parent probably should not be receiving 'Child Support' then, unless it is back child support that the other parent owed from beforehand or the children in question are attending school (including post secondary, even if they are not living at home anymore). Different jurisdictions have different rules, however, so you'll have to consult a lawyer familiar with the appropriate laws.
If the support order included a provision continuing support while the child was enrolled in college it does not matter where the child is living, as the support is to reimburse the custodial parent for the non custodial parents share of the child's expenses. If the child is attending school the custodial parent is likely still paying expenses for that child regardless of where they are living
The non-custodial parent must follow the child support order until it has been modified by the court. That parent can visit the court and file for a modification due to the change in circumstances. However, the court is not likely to change an order while the child is still attending high school. You should visit the court and ask to speak with a clerk or advocate.
no
Usually that is also covered in the divorce decree. If the parent chooses, most insurances will allow coverage as long as the child is in school, including college, until age 25.
