The first is Brahman or the impersonal void that you just merge into
The Hindu term for these people that want to merge into the void is Mayavadi
The second is Paramatma this is the form that resides in the heart of each and every living thing not just humans
The third form is Bagavan or the complete personal form that's full and has everything all in one basically. This form is considered the original and all the other aspects come from this one
These are the different aspects of the Hindu God
Not like the gods but that capital G God
Hope this helps
