Has or Have +had in one sentence?

Has or Have +had in one sentence?

I know this question might be duplicate.i am not able to getting the usage
of have had from another answers which is exist in stackexchange.So i
asked this question again.
I have examples.
1.Ann had a red bike for two years. 2.Sue has had a red bike for two years.
(3) I had a wonderful bicycle. (4) I've had many wonderful bicycles.
(5) In his lifetime, Uncle Alex had several red bicycles. (6) In his
lifetime, Grandpa has had several red bicycles.
Explain the difference between 1 and 2 ,3 and 4 ,5 and 6.
It would be better if you will take time to explain my examples.
Thanks
