Spray foam!

theres rated spray foams that act as a insulation and a vapour barrier. if you are using a can like great stuff it is not a rated vapour barrier spray foam.

Spray foam!

both open and closed cell are insulators. open cell is much more vapor open, and is usually painted w/ a vapor retarder paint if a vapor retarder is needed.

Spray foam!

Depending on applied thickness and foam type, yes.

Closed cell, as jklingel said, is not vapor open and at sufficient applied depths, does qualify as a vapor barrier.

You don't really need to thick of a vapor barrier on concrete as much as you need to thick of condensation resistance and an air barrier.
