is there any rules between wallets to have Special bitcoin address ?
No.
and i see many wallet give for 1 user more than 1 address (HD wallet)
Yes. You should use a new address for EVERY transaction.
An address is like an invoice number. It allows you to identify who is paying you, when they paid you, and what they are paying for.
You wouldn't re-use an invoice number, why would you re-use an address? Then if you receive two similar payments you wouldn't be able to determine who they came from or what they were for.
so after 10 years if number of users increase can two users get same address ?
No.
The quantity of addresses is MUCH MUCH TOO BIG for humans to ever use them up. The probability of two humans ever having the same properly generated address in all of human history and future is effectively zero.
