Help identifying coins. -- Ajuda para identificar moedas.

I recently acquired these four coins and haven't been able to identify them. If anyone can help, please let me know. The seller informed me that they were found during an excavation in Afghanistan.

Adquiri recentemente essas 4 moedas, não consegui identifica-las, quem puder ajudar. O vendedor me informou que as 4 foram encontradas em uma escavação no Afeganistão.

These are the coins

São essas as moedas:

Coin 1: Coin weighing 3.2g and measuring 14.70mm in the smallest diameter and 14.90mm in the largest.

Moeda 1: Moeda que pesa 3,2g e tem como medidas, no menor diâmetro 14,70mm e no maior 14,90mm.

Coin 2: coin weighing 2.9g and measuring 15.20mm in the smallest diameter and 16.20mm in the largest.

Moeda 2: moeda que pesa 2,9g e tem como medidas, no menor diâmetro 15,20mm e no maior 16,20mm.

Coin 3: coin weighing 3,1g and measuring 14,45mm in the smallest diameter and 15,25mm in the largest.

Moeda 3: moeda que pesa 3,1g e tem como medidas, no menor diâmetro 14,45mm e no maior 15,25mm.

Coin 4: coin weighing 3,1g and measuring 14,25mm in the smallest diameter and 14,72mm in the largest.

Moeda 4: moeda que pesa 3,1g e tem como medidas, no menor diâmetro 14,25mm e no maior 14,72mm.

Sorry, I know the conservation conditions are not the best and I don't even know if the position of the coins is correct or upside down, if anyone can help I would be very grateful

Desculpa, sei que os estados de conservação não são dos  melhores e nem sei se a posição das moedas estão certas ou de ponta cabeça, quem puder ajudar fico muito agradecido

Coins ## 1, 3 and 4 seem to be from the same ruler. The style of coins ## 3 and 4 is similar and they may well be the same coin. However, some of the pictures are upside down: #1 photo 2, #4 photo 2.

I think the text reads upwards, i.e. from the bottom, but the legends are incomplete and, on top of it, clumsy. It helps a bit that there are three coins with approximately the same legend, so very tentatively:

abu al-^cAl-

Muhammad ---

al-sultan

So: al-sultan Muhammad — abu al-^cAl---. This has got to be wrong in some parts, but maybe someone who knows the rulers of Afghanistan or Mughal India will recognize enough of this for an identification.
