Excellent! good luck!

Yes. It's correct.

Perfect !!

No, this is wrong Japanese unless you want to learn Japanese by making it only grammatically correct which seems quite useless. We never write nor say, 私の名前は、this is the same as saying, ''I have ten years old'', just to give you an idea. We say and write, サミュエルと申します　Or サミュエルです、please don't learn incorrect Japanese.
