Definitely not. Bellatrix hates Snape and is suspicious of his loyalty to Voldemort. Plus he is a lowly half-blood.
His name is Snape.
Well, the books are quite misleading and you don't find out until the near-end but yes ("Sanpe") Snape is on Dumbledore's side
No.
Bellatrix LestrangeWe don't know the extent of Professor Sprout's ablities. All we know is that she fought in the battle of Hogwarts and survived. She was also the Herbology master and knew how to handle extremely dangerous plant that she can use against Bellatrix.

Bellatrix is a star

Snape follows Lord Voldemort because he needs to know what he is up to so he can report to the portrait of Dumbledore, hanging in his office.
No! Quite the opposite, actually. They hated each other's guts.
No.
