I've got it i got it, I get it

Amy said, "Do you understand what I mean, Tom?"

Tom replied, "I get it."

1. Can I use "I got it", and "I've got it" to replace "I get it"?
2. What are the differences in usage among the above 3 answers?

In that context, both are OK, but "I've got it" would be unusual.

BrE would use "I get it" and "I've got it", but not "I got it".

The original is the most natural for me.

I agree. The question is posed in the present tense, so it's a variation on "Do you get what I mean?" so the natural answer would reflect the tense.

I'd use the present perfect as an answer to Have you understood?, especially to someone shouting.

"Have you understood?" while grammatically OK, would seldom be used where I come from. I would expect to hear: "Do you understand?" or simply, "Understand? or "Understood?"
