The name of God of Israel - El

[The following discussion is based on the detailed Wikipedia article "Names of God in Judaism". There are, however, some additions and changes by me so check your sources!]

El
This is a personal name of the Canaanite king of the gods, El and frequently appears in Ugaritic texts. El is a rather passive high god on the seat of the king while the young weather god Baal is active in the Canaanite pantheon. The female counterpart of king El is Elath.

The word appears in Hebrew especially in patriarchal narratives

El elohe yisrael El the God of Israel Gen 33:20
ha'El elohe abika El the God of your fathers Gen 46:3

The personal name El appears in the Bible often with attributes in the generic meaning of God

• El Elyon The Highest God Genesis 40:17
• El Shaddai God Shaddai Exodus 6:3 Probably comes from the Amorite god Shaddai  (City of Tel eth-Thadyen on Euphrates in northern Syria)
• El Olam Everlasting God
• El Hai Living God
• El Roi God the Shepherd Genesis 16:13 Hagar
  
• El Gibbor God the Hero

El is used as part of personal name

• Ariel God's Lion
• Daniel God's Judgement
• Gabriel Strength of God
• Immanuel God with us
• Ishmael God hears
• Israel God is my strength
• Michael Who is like God?
• Raphael Medicine of God

The word also appears in other Semitic languages.  For example in Arabic

• Allah God 
• Allath pre-islamic Arabic word for the spouse of God (compare Elath)

Elah
Elah, plural elim, is Aramaic and may have the meaning of fear, reverence. 

In the Bible name Elah only appears in the single Aramaic verse of the Book of Jeremiah and in the Aramaic sections in Daniel and Ezra

"Thus shall ye say unto them: `The gods that have not made the heavens and the earth, even they shall perish from the earth and from under these heavens.'" Jeremiah 10:11

• Elah-avahati God of my fathers, (Daniel 2:23)
• Elah Elahin God of gods (Daniel 2:47)
• Elah Yerushelem God of Jerusalem (Ezra 7:19)
• Elah Yisrael God of Israel (Ezra 5:1)
• Elah Shemaya God of Heaven (Ezra 7:23)

Elohim
Is common in the Five Books of Moses. Masculine plural "honorary" as in the word shamaim for heaven(s).

The word is used as a singular word for God.

There are some cases were the word has plural meaning as for example Exodus 20:3 "Thou shalt have no other gods before Me".


The use of Elohim as the word "God" in major portions of the Five Books of Moses has been taken as an indicator of a major literary source for the Pentateuch called the Elohist.


Eloah
Possibly a singular feminine form of the word Elohim.

The word appears in poetry and is found 41 times in the Book of Job. The Hebrew of this book has also other special characteristics in grammar and vocabulary and may represent some ancient dialect perhaps spoken in some area famed for wisdom (Bosra?).
