    Hi i have a simple question.
    Will 2 zener or 2 avalanche diodes work in series? For example will 2 100v zeners/avalanche diodes in series, clip the voltage to 200v?

    Yes, if you have 2 zeners in series the output voltage will be (max) their rated voltages combined. so 2 100V Zeners in series will read 200V if more than 200 V is applied to them

    I would recommend testing this first just to be sure, in theory it should work but doing some quick searches yields some contradictory results.
