re: Can the apple tv(1st gen) have KODI installed on it like the fire stick?

If it's white and looks like a Mac Mini it's the first gen, second and third gen are almost indistinguishable (the little square black pucks). If it is a second gen, it is technically capable if it hasn't been upgraded past a certain firmware version (I forget which), while the third gen isn't possible to install kodi on.
