Does this work on a Lenovo A9 - 9420 laptop?

The Ram clock speed for your A9 APU might down clock to 2133MHZ! But running in single channel will clock it to 1066MHZ like DDR3L! I wouldn’t put this stick of DDR4 ram in a DDR3 machine! It might not post on the first boot or it might not boot at all!

I have m471a1g43db0 -cbp in one slot. will this be compaitible with it in 2nd slot to expand to total 16 gb

It should, your old memory is slower speed

Will this work with acer Acer Aspire 5 ?

Are you swapping out a single module, or adding RAM to your machine? If adding RAM, you really should pair the exact same type of module with it, (DDR rating, speed/bandwidth, latency, etc), just open your laptop up and look at the sticker on the module itself. If you are replacing a single module to be used on its own, then yes this RAM should work in the Acer aspire 5, it uses DDR4 and the 260-pin sodimm form factor.

Does it wortks on lenovo 81w10094us laptop?

if you have available DDR4 260pin DDR4 memory module, then yes
