As for the lottery tickets, you don't need to do anything with them... maybe you'll win a prize someday!
I don't know SatsFaucet. I used to work with TrustDice, but then I checked the withdrawal requirement and immediately stopped using it! Things might have changed, but as I remember, you can only withdraw after either depositing or betting a certain amount. ...
One site that is legit is Cointiply. I successfuly withdrew some BTC from Cointiply earlier this year. The only thing to point out is that they convert your deposit into "coins" at a rate of 10,000 coins per $1, so if you want to withdraw after Bitcoin has gone up in value, you will end up with fewer sats!
