What it mean the name Alexander Esam Abood in Chinese and what it is it’s calligraphy?
Chinese do not usually translate foreign names by their meanings, we transliterate them.
For example, we do not translate the name 'Armstrong' as '手臂(arms)强壮(strong)' ; we transliterate it as '阿姆斯特朗 (Āmǔsītèlǎng) in Mandarin and '岩士唐'(ngaam4 si6  tong4 )  in Cantonese
'Alexander Esam Abood' could be transliterated as 亚历山大 伊泌 亞甫戶 and the meanings of individual characters in this transliteration are irrelevant.

Alexander means protector of men.
Esam means the one who guard.
Abood means unity.

If you know the origin meaning of the English name, you can just translate the origin meanings.

&quot;Alexander Esam Abood&quot; means &quot;the one who guards, protects and unifies men&quot;
&quot;亚历山大 伊泌 亞甫戶&quot; 的意思是 &quot;守护，保护和达成统一的人&quot;
