A is 8 times older to B
Does this mean (a) A's age = 8 * B's age or (b) A's age = A's age = 8 * B's age + B's age?
Similarly what is the meaning of A is 8 times older than B?

Does this mean (a) A's age = 8 * B's age or (b) A's age = A's age = 8 * B's age + B's age?

It's not really correct to say A is 8 times older than B, because that would imply that being older has a distinct value that can be multiplied by 8. That is why it's hard to understand what it means.
Mathematically speaking, to say that A is 8 times older requires you first to decide how much older one unit is. In other words:
C is 6 months older than B.
A is 8 times older than B, than C is.
Therefore A is 4 years older than B.
But this is an English forum, not a Maths forum.
So the best thing to say is: A is 8 times as old as B.
Then it's obvious that A's age = 8 * B's age.
Your sentence is wrong. The correct version is,
A is 8 times older than B.
It means,
A's age = 8 * B's age.
