Welcome to Numista!
The first two are definitely "bull and horseman" billon jitals. I think the third probably is also, it's just not as clear. These coins are from northern historical India (including parts of Pakistan and Afghanistan). Millions of these were made, generally between 900-1300 AD, by numerous rulers, in dozens of varieties. It is often difficult to determine the variety. Yours look like later versions, relatively small and with low silver content. Here are a few good sources of information.

Robert Tye’s book Jitals is also a great resource. It’s available as a free .pdf download (with registration) from

With the coins in hand it might be possible for you to determine the varieties.
In future it would be helpful to take coins out of the holders and photograph them in better light, and to list their weights to the nearest tenth of a gram.
