Can I get my address back?

I use a custodian wallet for transaction and don't re-use any address.
Yesterday I decide to click the place I circle in the picture and different address was coming out. Then I was still clicking it so that the first address can come again but it did not come.
My question is
If I want to get my first address back. How many time will I click so that I will get back to the first address. Or had any address that past has past. If yes. What of If their is matter that they want me to generate that particular address back from my wallet. What will I do?

Please don't be tire for my question. I rush bitcoin before and only know small theory but now I see this forum. I want to learn the practical well good because bitcoin as am seeing it will be with us for upto 50 years or 100 years .Now is morning for bitcoin
