What is my hair type? Maybe 4a/4b?

It's hard to tell because you don't have your ends exposed in any of the pics. Try taking and posting some new pics of your hair, freshly washed and without any product or styles on it (i.e. rollers, flexi rods, perm rods, etc.) and perhaps someone can help you then.
Yeah, what SweetRellie said. You just showed your roots pulled taut, not your actual hair texture. You should take the curl pattern quiz -- http://www.naturallycurly.com/hair-types it's on the right side of the page.
