Do your 56mm filter paper fit a diameter outside: 50mm filtration flask?

No _ I had to cut them down ; 50 mm papers seem hard to get 😞

Do you offer a filter paper to fit a 94 mm buchner that is a smaller micron than 20 ?

Dear Customer, Sorry, we currently only have filter papers that feature 20 Micron. Thanks, Lizzy L

Dear Customer, The item is for laboratory use only. Thanks, Lizzy L.

What is the temperature range they will work with and which solvents are compatible?

For my purposes filtering will be done below freezing so wouldn't be much help as far as your question the range of working temp. It is not specified on packaging but filters seem solid
