kill 57 enemies with headshots without dying or becoming downed

this one is still manageable, i mean.. you can pretty much use tanky warframes like valkyr to sweep up the map with headshots. That 57 is not in one mission, so it's fine.

25 finishers without taking damage

this. this is a bit crazy, what a damn luck you have there. But If assuming it works like above, not just in one mission. It's still possible to open it. Use Ash, but if you got hit once then the counter will stop, repeat on the next missions until you get 25 finishers. Good luck.
