Welcome to Using English!
With your #2 above, I'm not sure if it's supposed to be a tag, as above, or the word "now." Is this a good time to call? Can I call you now? (Something that would be went in a text message, perhaps.)
#3 seems to be "now." You weren't okay before. I want to see if you are okay now. Are you okay now? I heard you were really ill over the holiday. Are you okay now?
