Answer 1

i would say single

Answer 2

I think it's the single crochet.  It uses more yarn and it's not as likely to show a hole.

A half single crochet.

Answer 4

It's half a single crochet--that's where you have your loop on the hook, go into a stitch, grab the yarn and pull it through both the stitch and the loop together.  It comes out small (short), but it is very thick and tight.

Of the ones you named, however, it is the single crochet.
