English into Japanese

八人の保護者

I asked for this from an exchange student and have copied his reply to me verbatum i hope it is helpfull
I think the "lit" means a literal translation the questionmarks are probably japanee characters that wont translate properly to english text.

I'm gonna venture a guess on this. Try 八人の後見 = はちにんのこうけん = hachi-nin no kouken = lit. "eight people who are guardians"
There are three words in my dictionaries that are translated as "guardian", but I think kouken fit the bill best. Kouken, as a term, usually refers to someone who helps you, supports you, and defends you, but who still lets you be the center of attention. It's usually used to describe kabuki stagehands, but I after a bit of research, I can't find any reason why it can't refer to any sort of guardian. You may want to get a Japanese native to look over that to make sure it captures the proper subtlety.

Thanks, I'll do that.

後見 fits this definition of "guardian"

Law One who is legally responsible for the care and management of the person or property of an incompetent or a minor.

so, it is really hard to say out of context
