Underneath, you see "Almalk" in Arabic. Almalk or Al Malik ,as we pronounce it easier, is today usually translated as "the
king".
The first picture shows the word in clean,
standard Arabic.
The second picture shows it in calligraphy. Although the "l" is the second letter the pen has started with, the line continues in putting the round "m" before it.
(Attention: we are
writing right to left. This is Arabic.)
Like the second picture shows the word, it is to see (between two horizontal lines) on the
reverse side of both coins of the previous message.
Also your coin number #7 shows it and I believe, this piece too is a Mamluk coin of the same period. especially because the
obverse shows a same twisted
wreath.
As tird picture, I repeat the two coins here above and as fourth I show your number #7 coin, to compare:
