1. I want to sign up for the after school activity.
2. I want to apply for the after school activity.
3. I want to enroll the after school activity.

Do the above sentences mean the same?

2. I want to apply for the after school activity.
3. I want to enroll in the after school activity.

Do the above sentences mean the same?

"Sign up for" and "enrol in" mean the same. "Apply for" is different. If your application is accepted, you would then sign up or enrol.

Note the BrE spelling of "enrol".
