Pretty much this.

release them,call the police and tell the principal.

Follow the general theme of ‘help them while maintaining their decency/reap potential benefits of my actions’. Then go punch Snips and Snails in the gut.

Untie them and give them as many clothes as I can give so they can go home decently.

Wonder why I’m still in high school.
 
Then free one of them, and ask what the heck happened. Then free the rest.

I have a good laugh at their expense.
 
Then let them go.

Tease them briefly, of course. But then of course let them go.

Genuflect.

Rape.

this is 911, please state the nature of your medical emergency

Free them, then leave Canterlot High and look for a portal to proper Equestria.

The same as here >>481217, ie. “I dunno”.
 
I suppose I could discreetly take some photos, then untie them.

Probably let them go since I’m not a rapist.

Untie one of them, ensure they’re okay, get her help and untie another two… then run off with one while they’re distracted with the last one.
 
Unless I have a way to get them to my place without attracting too much attention. Then they all become my cuddle girls.

Freaking ninjaed.

Cut them loose and throw a towel/jacket over them to insure they maintain a shred of decency… what else would I do?
