Do you know how to use the search - it includes different alphabets and numbers,
including Arabic for your [upside-down] first picture. The coin has ٢ and ١٣٧٦ which
when searched for gives 54 results, including this ... https://en.numista.com/catalogue/pieces7840.html
Here is a picture of what I did ...
1. Click on the symbol for Special keyboard
2. Which brings up this line
3. Choose the style, which will be Arabic
4. Type in the numbers
5. The number of results.
Please show both sides of coins.
Sometimes they have one side the same for various denominations.
Also your 2 + 2 + 1 = 5 pictures are they meant to be 5 different coins?
If so then 1st and 4th pictures are the same.
Also important is add the diameters as well.
So now using the Special keyboard maybe you can find what the others are yourself.
Lastly, maybe it is the lighting, but on pictures 2 and 3 I see no numbers -
which is why I said show both sides, as that is where they are I think.
The 5th picture has ١٣٤٠ on which in my search just now has 140 results,
including a coin from Afghanistan which may be yours.
The results can be reduced if the diameter were known.
Such as if that coin were the 23mm I guess it is, then a range of
say 22-24 entered as well would give only 18 results.
Further reduced by the metal; and so on.

This a 2 piastres (qirshan) from sultanate of Oman. The date is Hijra not AD. si you need to add almost 650years to Hijra dates to get the Gregorian calendar date.

The second coin in your first post is Algeria, 10, 20 or 50 centimes 1964. The exact denomination is on the side you didn't post. So always makes pictures of both sides and give weight and diameter. With weight and diameter a proper determination was also possible, even without the reverse picture.
Please learn about reading Arab dates and then turn the images accordingly. It's a small thing to ask, but if you're really interested in this hobby, it's a must.
