It would depend on the context.
We had the day off because it was our teacher's training day (only one teacher was being trained)
The whole school was closed for teachers' training (more than one teacher was being trained)
There are three possible options for your question. If you are referring to more than one teacher, there is no apostrophe (teachers). If you are referring to an object that belongs to one teacher, the apostrophe is between the r and s (teacher's desk). If you are referring to an object that belongs to more than one teacher, the apostrophe is after the s (teachers' break room).
Depends, if the word "teachers" is a plural noun, and refers to multiple teachers then use an apostrophe. Example: The teachers' club handed out free pencils. If the world "teachers" is singular, and only refers to one teacher, then use an apostrophe like so: My teacher's dress is very red. If you are not referring to possession at all, and nobody is owning anything in the sentence, then put no apostrophe

The apostrophe will come after s. (James')
This is the case when it is the plural possessive form of teacher. This means something belonging to more than one teacher. If something belonged to only one teacher then the apostrophe would appear before the 's'. - "The teacher's diary"

Yes, when indicating possession for multiple people, you add an apostrophe after the "s" at the end of the plural noun. For example, "the teachers' lounge" refers to a lounge belonging to multiple teachers. If the noun is irregular and does not end in "s," you would add an apostrophe followed by "s," as in "the children's toys."
It means that the plural noun before the apostrophe has possession of the noun or plural noun that follows it. Example: All the cats' tails were wagging.
If you're talking about something that belongs to the teacher, then you need the apostrophe. Teacher's desk, teacher's computer, etc. If you're talking about teacher as a plural noun, then you don't need the apostrophe.
