is there a 4th Abrahamic religion or is there more than this?

Not that I am aware of. The three that I know is Judaism, Islam, and Christianity.

Probably man will. I never limit man and his ability to create new ways to think of old ideas and concepts.

Later.

Baha'i claims to be an Abrahamic religion, though it has none of the central characteristics of one.

But if you claim to be an Abrahamic religion, you are more likely to be listened to by Christians and Muslims (Jews are too clever).

That is a large potential market.

Ḥanīf ,Judaism,Christianity and Islam .

there is one called Mandaeism but I think it's a pre-Abrahamic religion

There are 4.

Judaism, Christianity, Islam, and Bahai.

There were other texts at the time of Messianic figures like Jesus and no I hope no one turns one of them into a religion PLEASE we don't need more problems
