Can't identify the rulers! [solved]

Hello my friends, these three silver coins (possibly Half Tanka denomination) from my collection are I'm guessing from the Gujarat Sultanate, but I'm unable to identify the rulers and mints, are these coins even rare? These are all weighing 17.1 grams, so around 5.7 grams each. I'm thanking you all for going through these historical pieces :)

Yes, half tankas of the Sultans of Gujarat, all from Mahmud Shah I. 

The second and third coins are the same: this one

Mahmud Shah I, Muhammadabad, Goron/Goenka G110

The first coin is similar to this one (different dies)

Mahmud Shah I, Muhammadabad, GG G103

For future ID requests it would be helpful to post individual weights and diameters.

You made my day. Exact matches they are. Thank you so so much for the help :)

You're most welcome. Bengali hospitality is of course legendary, and I've been the fortunate recipient before. Am glad to repay a little.
