No it is not.
Added: Unless you are both adults.
It depends.
If you're in college, that's fine if the teacher is somehow your age.
If not, that's totally messed up in so many ways.
It Is Okay!
Yes, it is always okay to kiss a friend, whether the friend is male or female, as long as your friend is okay with it.
no.
Yes if it's okay with the teacher, especially if you're in kindergarten and can't remember your teacher's name. No if it's not okay with the teacher. I would ask first. It may be disrespectful. If the teacher says okay, be ready to be called student, green shirt boy, etc.

A father shouldn't french kiss his daughter.
No.
If your lucky and the teacher is beautiful and good looking, go for it.

No, it is not okay for a teacher to grab an autistic child by the wrist. For that matter it is not okay for a teacher to grab the wrist of any child, this would count as assault.
