I know the main one is Laveyan Satanism, but I know that there are many more like theistic satanism.
What are they and what are some basic descriptions of them?
Sources?
The Bible is not a source.
Just say in'. I usually run in to a few people who think it is no matter what type of question I ask.
What are some Satanic symbols and their meanings?
according to the quartet Al Yezid, Satan is still one of God's top angels and should be honored as the king of Angels. The Fall of Lucifer was a trick supposedly purported by the human writers of the bible to turn them away from Lucifer's power and Assistance. The Yaziddi can be found in Northern Iraq.
Also "Theistic Satanists venerate Satan as a supernatural deity, whom some[who?] consider to be entirely benevolent. In contrast, Atheistic Satanists[1] consider themselves atheists and regard Satan as merely symbolic of certain human traits."
The yetis believe in Melek Taus or the Peacock God.
The sacred book is called the Black Pearl of Melek Taus.
There are too many really to say. Few try to get into the public eye as much as LaVey did.
Satan looks at you and says, "Silly human, did you really think I care if you like me or not? My job is to make people FORGET about God, not go against him. Ready for some eternal suffering?"

Actually, there isn't.
There was NO religion called "Satanism" until the founding of the Church of Satan in 1966 by Anton Szandor LaVey. The principles of this non-theistic religion can be found in "The Satanic Bible", written by the same man. So since the Church of Satan was the first, it seems silly to call something with completely different dogma a "form of Satanism".
Granted, throughout the centuries you had the occasional group of bored aristocrats who'd do a "Black Mass" for sheer entertainment value. Or the occasional devil worshiper who based all of their information on propaganda stories from the Catholic Church. But again, no actual religion called "Satanism", and no dogma other than just being blasphemous.
There's already a name for people who believe Satan is a deity and worship him: devil worshipers. Why use the label for a completely different belief system, "Satanism", to define them? It makes no sense. It would be like calling Mozart "alternative rock". This isn't like Protestants and Christians pointing the finger at each other and saying "You're not a real Christian"; they still use the same book and the same deity structure. Not so with Satanists and devil worshipers.

Our primary symbol is the Sigil of Baphomet. You can read about it here:

We also use the alchemical symbol for brimstone on occasion.
What Scorpio_Sun_Cancer_Moon said.
And: Theistic/Pagan/Spiritual Satanism & Atheistic Satanism.
The other one is filled with the silly-poos (nice way to put it) that believe Satan is evil. Oh wait. Those are Christians.
