Yes, transactions performed on The Sandbox's marketplace will require $SAND, which is the currency of the platform.
There is a 5% processing fee on all $SAND transactions. This fee goes back into the Foundation, which is used to fund artists, creators and their fantastic projects.
Meta transactions within the marketplace will eliminate gas fees.
You can sell ASSETs, LAND, GEMs and you will also be able to rent out LAND too.
This is up to the seller. However, they will need to be fair and competitive in order to attract a buyer. Factors such as quality of ASSETs, uniqueness of ASSETs, size of LAND, location of LAND and so on need to be taken into account in your pricing in order to attract the right buyer.
$SAND is the currency of The Sandbox, so all sales within the marketplace will be in $SAND.
There is a small fee to upload ASSETs onto the marketplace. This is primarily to discourage the spamming of low-quality ASSETs being uploaded to the marketplace. Genuine artists who upload high quality ASSETs will make this fee back quite quickly and then go into profit.
