To remove someone from your Twitter account, go to your account settings and navigate to the "Security and account access" section. From there, select "Apps and sessions" to see any connected apps and sessions. If someone has access through an app, you can revoke their access. Additionally, you can change your password to ensure they are logged out and cannot access your account again.
Go to their profile and click "block".

If someone blocked your profile on Twitter, it means they don't want you "following" them. If you proceed to get around the block by hacking into their account, this is illegal. You will be kicked off Twitter and will face possible legal consequences, per Twitter's terms of use. If you feel that your privacy has been violated or your account information has been hacked into, please refer to the link at the bottom of the page from the official Twitter website.
