Sorry, but please don't bump your threads within minutes of posting them. Folks will read/respond when they are able. It's very annoying. Also, please consider posting multiple images in one post. It's just good forum etiquette.
Ok, annoyances aside, Not 100% on the first, but maybe E tennelus. The second looks like a bacopa of some sort, and the last looks like an Echenodorus of some sort. Sorry I can't be more specific!
Edit: I've merged the posts into a single post.
