Use DAPI/HOECHST at the same concentration you use for cells/FS
I use Hoechst H33258 Sigma 10mg/ml soln
I dilute by adding 0.5 microL to 100 microL buffer then add 1/100 to Alexa secondaries ( final 1/20K diln factor)
Some incubate in HOECHST or DAPI after secondary ab incubation, for IF
Sure, if only "staining" nuclei, incubate in 1/20K Hoechst in same buffer
This will vary for each lab
Or, buy mounting medium that contains DAPI

Good luck
Carl
