First pic I agree with aculeus
2nd pic looks to me like cerealis but depending on your flow conditions you may be experiencing reticulate evolution which will change the way it branches, etc. making it almost impossible to accurately id without looking at a piece of skeleton under magnification.
3rd pic - The pic kind of resembles granulosa but it's tough to tell for sure from that angle. my guess is A.willisae or maybe anthocercis. I used to have a colony of anthcercis that was almost that color with a similar growth pattern around the table edges.
