What do I say in Japanese when I'm trying to imply, "This is my dad", "These
are my parents", "This is my friend(female)" or "This is my manager"?

I don't think using `これ` is polite, nor will `彼` be appropriate.

A polite way to say " this person"
You do not need anything. Just list their title and add desu.

  * This is my dad: 父です or オヤジです。
  * These are my parents: 両親です。
  * This is my friend (female): 友達です。
  * This is my manager: マネジャー（上司）です。

The alternative to これ in polite Japanese conversation is こちら (you should find
it in most 初級Japanese text books on how to introduce yourself.)

To implement this （borrowing Dono's answer） I would say:

> こちらは私の父です。 This is my father.  
>  こちらは私の両親です。These are my parents.  
>  こちらは私の友達、由美子です。This is my friend Yumiko.  
>  こちらは私のマネジャー（上司）です。This is my manager.

You can even use this to introduce yourself on the phone:

> [あの..]こちらはABCのVenkatesh Kumarですが[いつもお世話になっております。]

The stop gap alternative to referring to people by pronouns (he/she/you etc)
is to use their name. You would attach the suffix (さん etc) according to the
relationship between you, your 相手 and your colleague.friend etc.
