Would U plz correct this sentence?

Hi,
I was wondering if anyone would tell me about the underlined items, "comma" in special.

“...has always been accompanied with lots of nice, memorable and evocative memories for all of us.”
What's the rule for putting commas among adjs? Is any comma needed between the following adjs? Thanks in advance.
“...this sweet pure period of life...”

I would change "with" to "by". There should be commas after "sweet" and "nice".

Thanks a lot...

Does the first sentence sound natural to native speakers? Cheerio!

I would leave out "memorable", it's unnecessary.
