Is this capable of downscaling 4K to 1440p with a 4K 60hz dummy plug in the first output and 1440p monitor in the second out?

1080p is what's supported haven't tested at 1440p but it's got pretty good smarts inside.

Does this support rgb 4:4:4 at 4k 60hz?

Hello, No, this unit supports 4:2:0 at 4K 60Hz.

Do both tv's (outputs) have to be "on" simultaneously for this to work? Looking to split my xbox signal between rooms (short hdmi cable run to both)

Both TV’s do not have to be on at the same time.

If i want to send a 4k hdr/dolbyvision signal into the splitter, can i have one output be unaltered (4k+hdr) and the other be 1080p with no hdr?

Yes, I just tested this with a 2080 ti to the device, and then out to my 4k hdr monitor on output 1 and to my 1080p projector on output 2. It works fine in RGB limited and full. Keep in mind the signal to the non-hdr display will be a "flat" / "raw" color profile. So it won't look very good without serious tweaking on the secondary device, but it does work.
