Help to identify Antique/Antiquity Indian Silver Coins

Hello all,

I photographed them in groups for their classification, please help me to identify them. Start from left to right - top to bottom.  Regards.  Juan.

Group 1



Group 2



Group 3



Group 4

All are from Indian princely states - Gwalior. They have the typical bow and arrow symbol on them.
The weight will help you determine if they are 1/4 Rupee or 1/2 Rupee or 1 Rupee.
I will try to identify the rulers on each coin later  
 

they weight between 5.4 to 5.6 grams. Yes please it will be great to know the rulers.

They should be 1/2 rupee coins of Jiyaji Rao. we have 1 rupee coin of jiyaji rao, https://en.numista.com/catalogue/pieces54058.html in numista

In relative terms, how rare are 1/2 rupees of this ruler?
