1. What are a few good Crypto exchanges?
The right place for this is on the
exchange child board.
2. what are some good Hardware wallets?
3. I assume that when i send crypto to my hardware wallet, i use the wallet address ? so any wallet i choose this can be accomplished?
4. from what I understand that when I use a hardware wallet , the crypto I purchase is actually not on the wallet but stored on the block chain? if so, could the block chain be hacked? has it before?
5. what is the most secure way to store crypto?
This could be brought to the more general
Beginners & Help board, as the question concerns hardware wallets and wallets.

There are many cryptocurrencies. There are tokens and coins. Besides Bitcoin, these are all what you're referring to.
And at the very least, you can read the posts already made by several people here.
