HDFC Infinia Add-On Cards: Seeking Guidance

[stech18]

I'm holding HDFC Infinia considering add-on cards for family. Can anyone share insights on:

1. Limit: Is there a maximum number of add-on cards allowed? I read somewhere it's 3, Can anyone confirm it.
2. Relationship: Must add-on cardholders be blood relatives?
3. How do we add guests on domestic lounges? Does Mastercard variant accepted in lounge or will always have to use priority pass?

Your experiences and advice would be greatly appreciated. Thanks!
