Pul - temp. Golden Horde -residue. [solved]

Have a nice day and health.
I guess I was able to determine something and I'm just guessing some. This is the last requirement of this difficult section.
That's how I evaluated it:
1, rather bronze than copper, 2,32g , 19,8x 18 mm, th.1,32 mm
Mongol States › Golden Horde-Pul - temp. Tokhtamysh khan-
ND (1378-1395) - I can't specify the date?

2,
Copper , 0,82g, 18,0x15,0 mm, th. 0,80 mm
Mongol States › Golden Horde
Pul "Sun-face type" - temp. Toqta khan Solkhat mint

Lebedev m8a


3+4 , they are the same-
Copper
a, 1,62g, 18,39mm b,1,30g, 18,65mm
Pul - Muhammad Öz Beg Khan Qrim al-Jadidah mint

a,
b,

5, And here I resigned after a week of searching the web -I think the dump of history

copper, 2,48g, 17,6 mm, th. 1,66 mm
??

I took my studies -and it gave me a lot of new things -I will quit Islam in a moment and return home.

Hello Ivan,

1. Your identification is correct. This is a type without date. I should have been deleted all the date lines on the Numista page before...)
2. The coin is in too bad shape. Maybe it is one of these types

3-4. Correct

5. Maybe some flower type, but it is not possible to id with this shape...

Have a nice day and health.
Thank you so much, yes, the first one mistaken me for so dates. You helped a lot. The first one was the one I wanted the others were forced but at least something in history was enriched by knowledge.
