Yes, if the membrane is permeable to, say 4 different substances, those 4 substances could diffuse back and forth at the same time. Also, the same substance could be diffusing in and out at the same time (i.e. sodium can diffuse in while some other sodium diffuses out). Just because a cell is in a hypotonic or hypertonic solution doesn't mean that every single diffusion will attempt to rectify the situation to equilibrium, though over time, it eventually will.

Welcome to the world of osmosis. Diffusion thru a semi-permeable membrane. I went to college 20 yrs ago, great Biology Professor, made it very interesting. He threw a piece of chalk across the room to illustrate-diffusion. Ask, your teacher or look in the book for your other question. Be challenged

Of course. If the membrane is permeable or semi permeable, liquids can travel in both directions as they seek a uniform consistency.

YES AS LONG AS THOSE MATERIAL ARE NOT THE SAME
SOME ARE HYDROPHOBIC SOME ARE HYDROPHILIC
