Question about volumes


I’m new in the world of Volumio, and i have some questions,

Can we use 1TB, 2TB, 3TB HDDs, as external drive for play music ? Or only 1TB MAX ?

Can i stream the song of my computer (Linux) to Volumio ?

Can i control Volumio with mouse/keyboard on my TV ? (RPi -> HDMI -> TV)

Can i burn the img with “dd” command ? (dd if=volumio.img of =/dev/sdb bs=1M)

Thank you
