How long until my eyelid closes fully after Blephoplasty? I am 5 days post OP and as time goes by it feels tighter. (Photo)

I can understand your concern.  You have a  considerable way to go.  You will get improvement with time, but it is difficult to know if you will achieve complete eyelid closure with conservative treatments alone.  At this point I would be in close communication  with your surgeon.  Stretching and massage exercises can help considerably, and you need to protect your eye at night with a mask and ointment or taping, or other measures suggested by your surgeon. I am certain it will improve considerably, and hopefully completely with time.

Incomplete eye closure may occur following upper eyelid surgery. This is most often due to swelling and inflammation, particularly of the muscle that closes the eyes, and should improve as the swelling resolves. It may take a few weeks until swelling fully subsides so 5 days postop is still pretty early in the process. It is important to use lubricating eye drops throughout the day and ointment at night, until you are fully able to close your eyes. Another rare cause for incomplete eye closure includes excision of too much upper eyelid skin. I recommend following up with your surgeon.

Swelling can be variable and it can takes weeks to months for pull on the eyelid to fully resolve. The right eyelid may have had too much skin removed, which will not resolve on its own. Make sure you keep your eye well lubricated with gel tears, and tape your eyelids at night. Close followup with your surgeon is imperative to prevent long term consequences to your vision.
