when should i use "has", "have", "have been" ?

Can you help me with this question?
when should i use "has", "have", "have been" ?

 when you use "I, we, you ,they" as a subject, you shoud use 'have'

 when jubjedt is "he, she, it", The third person singular, you shoul use "has"

 "have been" is used in prensent perfect tense:

"have been done" is The Present Perfect Passive Voice

"have been doing " is Present Perfect Continuous Tense

 For example:

1. I have a book, she has a pen.

2. I have been there for three years.

3.He has finished his work already.

4.we have been seen by the police when we  get out the house.

5.I have been collecting shells for five years.
