is there any rules between wallets to have Special bitcoin address ?

and i see many wallet give for 1 user more than 1 address (HD wallet) so after 10 years if number of users increase can two users get same address ?

Absolutely not,wallets like electrum usually gives you 20-26 address to play with and plase do remember this addresses are your and only yours .
They develop their softwar in a random and unique way that even afrer 100000years there will be no same address.
I hope this helps.

If I'm not truly mistaken, the only way to really make sure there is no 2 same addresses would be to keep a list of all addresses somewhere. And that would, of course, be unsecure. Even if one program wouldn't give same key for different users, there are other programs so one wallet not colliding is not enough. I know, that this is very, very unlikely but theoretically speaking.

Edit: I don't know how that one wallet could do it, but if we imagine it could.
