I didn't get you. Ask with little more details.

Wish you a happy birthday. Many many happy returns of the day. May you be happy forever. May God bless you and keep you in peace and happiness always and forever.

They're not equal. They are completely different in uses and meaning. "Ever" is related with "never." I'll never do it = I'll not do it ever. Why ever did you come here? Have you ever heard of him? Never = negative ever

Say is used while one isn't communicating with somebody else. Say to (=tell) is used while one is talking to somebody else. Talk to is used while the work is in a running process They say you can't do it, which is wrong. He said to (=told) me he'd try. I'll talk to him.

names of feelings, subjects, objects, persons, goups, animals, plants and everything is called nouns. simply, name of something is called a noun. as example, Mark, Catherine, Rose, Universe, Army, Committee, anger, sadness, Human, Lion, Bird, Water Lily, road, drug etc.

Happy belated birthday is correct.

"has" is only used in third person singular number. As example, He/She/Mark/It/New York... has become famous. "have" is used all other times. As example, I/We/You/They/People/Mark And Robin/He and She/Mangoes... have become famous.

Has been (for third person singular number) / Have been (for other than that condition):- 1. as present perfect tense- I have been there. 2. as passive sense- The situation has been handled. 3. as present perfect continuous tense- It's been raining since morning.

A real thinker is you.
