Yes, they look good. I also wondered if they've not been blooming for 5 years? How have you kept them during that time?
Hippeastrum (commonly called Amaryllis) don't require a dormancy for blooming, and will choose when they bloom if you just treat them like houseplants all year.
Sometimes they skip blooming for a year-maybe two- to 'recharge' their strength.
