Here are some differences:
It this is a vague question, but if you compare the Hebrew alphabet to the English (Latin) alphabet, the biggest differences are that Hebrew has no letters for vowels, and it is written from right to left.

It depends on which alphabet you are talking about. Hebrew: אבגדהוזחטיכלמנסעפצקרשת Latin: abcdefghijklmnopqrstuvwxyz
Greek Hebrew Phoenician Egyptian and several others.
There is no ancient people that did this. While the Phoenicians developed an alphabet that gave rise to Hebrew, Greek, and Latin, the Phoenician alphabet is not still in use today.
Israel uses the Hebrew alphabet for the Hebrew language, the Arabic alphabet for the Arabic language, and the Latin alphabet for the English languages. Signs in all three languages can be found throughout Israel.
There are many differences. Here are a few: Arabic letters are connected. Latin letters are not. Arabic is written right-to-left. Latin is written left-to-write. The Arabic alphabet has no vowels. Latin does.
The Hebrews developed the Hebrew alphabet.The Greeks developed the Greek alphabet.The Romans developed the Latin alphabet.

First you would need to specificy which old alphabet you are referring to. If you are referring to the English alphabet, it was borrowed from Latin around the 8th or 9th Century CE.
The Hebrew alphabet was borrowed from the Phoenicians.
This question makes no sense. There is only 1 Hebrew language, and it has only one Alphabet: the Hebrew alphabet.
