Are the following sentences correct?

He is having $ 100.
I am having $ 100.

Is, "He has got $100" correct version?

Thanks MrP in advance.

He's not in right now, Paddy. May I help you?

The continuous is incorrect. The verb 'have' when it means 'possess' does not use this aspect, but rather the simple tense:

'He has $100' or 'he has got $100'. These are correct.
Thanks MM.
