The second one looks like some species of Cosmarium.

Very nice shots !
The second one is some kind of desmid, i agree with Michael.
The first one looks like a dividing astomatous ciliate, perhaps
something like Anoplophrya sp.
These ciliates normally live commensalic in worm guts..
You can see the long macronucleus very well..
