Hi

I am struggling to find what chord variants these are that i can enter into BIAB(if possible)

First, BIAB does not allow you to specify chord voicings.
Second, There is a complete list of all available chords in the help manual. This list has been included in the forum many times to answer just this question
Third, those are some dozy chords for guitar. I bet they could sound nice in the right context.

I'm not sure if this helps, but the 'Chord Builder' is available that may assist.

<Control><Shift>B

It lets you listen to the selected chord also.

Gave that a quick try to see what is there.... Not much to help here. Again there is NO control of chord voicing in BIAB. Chord voicing is that critical next level that you have to move out of BIAB to achieve. I have been enjoying how Scaler opens up this next critical level by providing complete control of voicing.

I told you all that Scaler was going to be the next big thing.

By the way, for alternate naming you could go with:
1) GM9#11

3) Em9
