Form should be focused on more than colour.
Both are HM, one however has far more branching than the other ressulting in the feathertail apperance.
By crossing a Vt to either of them you will get similar results. But the incresed branching in Male1 may compensate for the VTs low branching which will potentially give the offspring more caudal spread and therefore closer to HM standards.
Looking at male 1 again he appears quite short bodied, crossing this with a dt which are usually shortbodied will result in poor, shortbodied fry, plus it looks like hes carrying DT so you may get short bodied RTDT fry.
DT and male2 will most likely give you blue fish with red wash, same as what you would expect from male 1 and DT. They would have a nice broad dorsal because of DT influence.
red VT and male2 would prob give you blue with redwash and darkbodied reds with lots of blue irids.
Red VT and male1=probably again, blue with a lot of redwash and/or some reds.
This is just me guessing though.
At the end of the day its up to you, its like a lucky dip
