Absolutely not. It can, but you can't say that as a rule.
For instance, if you were to say...
A square implies that it is a rectangle.
It would not be true if you said
A rectangle implies that it is a square.

No. It can but does definitely not apply to all cases. A puddle doesn't imply rain (loose hose) but rain does.

If Jenny is a marsupial does that imply that all marsupials are named Jenny?

No. There may be several way to get to B other than A.

No, not necessarily.
Every bird as wings, but is everything with wings a bird?

No! Example;
An apple is green.
If it is green it is not necessarily an apple.

No.
Compare:
"This creature is a dog, therefore it is a mammal"
with
"This creature is a mammal, therefore it is a dog".

No, if A is false and B is true:
A -> B is true, and B->A is false.
