There are many different crab species. There are some crabs that are known to live in certain rivers.

I don't now
Yes, also oysters, sandbar sharks and blue crabs!
Billions: crabs, shellfish, birds, worms, mosquitos, and lots of even smaller animals.
Most small crabs in estuaries are detritivores
yes. whales like belugas can live in warm water estuaries :D
It is important to protect estuaries because they serve as spawning and nursery grounds for many ecologically and commercially important fish and shell-fish invluding bluefish, strip bass, shrimp, and crabs Hope this helps :)
"An estuary is a coastal body of water that is semi-enclosed, has a clear access to the ocean and at least one river or stream flowing into it. Because estuaries are transition areas between river and ocean environments, they are subject to the effects of both. Oceans have tides, waves and salt water; rivers have fresh water and deposits of sediment. Estuaries are some of the richest natural habitats on the planet due to having both the salt water of the ocean and the flow of fresh water from the river. The rich nutrients in this environment support many organisms. In estuaries we find many fish nurseries - fish such as salmon and sea trout, striped bass, flounder and eels; and migratory birds, such as the black-tailed godwit and the Canada Goose that use estuaries during migration. There are abundant bird populations living in estuaries. Because of the lush plants and plenitude of fish and other animals, there is much for them to eat. Birds such as sandpipers, great blue herons, great egrets and green herons commonly live in estuaries due to their long legs for wading and long toes that allow them to walk in mud easily. They have bills that are adapted for catching fish, worms, crabs and the invertebrates that thrive in estuaries. Some fish, such as striped bass, flounder and eels visit estuaries. Other smaller fishes such as stickleback live their complete life in estuaries. Animals such as mud snails and oysters, crabs, seahorses, turtles and rays live year-round in estuaries."
