It can be hand-washed in mild soapy water' rinsed and air-dried as long as the foam has not gotten crumbly with age.

Q: can the weatherseal go between the bottom of the air conditioner and the window sill?)

If there is space then yes. It’s a foam so you can manipulate it into the smallest crevices.

Q: does it absorb moisture?

Never had to experience moisture

Q: What is the maximum temperature rating of this foam?

Sorry, no idea. I use it for insulation. It does not come with temperature ratings listed, but as it's very light, thick sponge rubber I wouldn't think it would withstand very high heat.
