Other gods
In Hinduism, "other gods" can be, for most of the time, understood as a kind of "organs", "moods", or "dispositions" of One God and these "organs" or "moods" have their names. For example, a finger of One God is Ganesh, a fingernail Indra. Vishnu's followers often consider Shiva a manifestation of the Vishnu's energy; shaivists have the same opinion - Vishnu, according to them, is the manifestation of Shiva. However, opinions differ in the perception of Trimurti - some of them are even strictly monotheistic. Shakta followers perceive this similarly - Devi Mata is the Supreme Goddess of All. Unfortunately, "fingers", "organs", or "anger" of One God are seen by this Western or European culture only separately from the Main Body, so here is a conflict between the two cultures, which are incompatible in their thinking.
Exodus 3:2, There the angel of the Lord appeared to him in a blazing fire from the middle of a bush. Moses stared in amazement. Though the bush was engulfed in flames, it didn’t burn up.
Agni
Agni is the god of fire and a member of the so-called "Dikpalas" - a class of deities that govern specific directions (this teaching is also in the Kalachakra tantra).
It seems that Agni has a female touch in this picture.
There are four such Guardians of Directions
and these are called Lokapalas (Guardians of the world). These are:
Kubera - North (god of richness)
Yama - South (god of death)
Indra - East (god of war and weather)
Varuna - West (god of oceans)
Agni is the god of southeast direction.
There are many gods in Sanatana Dharma and most of them, except for Ganesh, Skanda, Shiva, Durga, Surya, Vishnu, are analogical to the Judeo-Christian concept of "angels" (Devas, but not so powerful as Maha Devas). Indra - god of weather and war, for example, is the ruler of these Devas.
Different gods were considered supreme at different times and it is possible that any of them could have more names in Rig Veda, and today they are known by a completely different name. Some of the earliest Vedic gods are: Dyaush-pita - the sky father, Vayu - the wind God, Parjanya - the rain God, Surya - the sun God, Varuna - the God of oceans, Agni - the fire God, Indra - the war God, Soma - the God of speech, Yama - the God of death, Adityas - a group of solar deities, six in number in the Rig Veda, eight in most of the Brahmanas, and twelve in the Satapatha Brahmana, Aswini - twin Deities, and so on.
Ayyappa
Ayyappa is a
Hindu deity revered in South India. Lord Ayyappa is
worshipped in a number of shrines across India. The Sabarimala
Ayyappa Temple (a pilgrim centre in Kerala) is unique
in all India. Devotees of this god show no caste or religion
discrimination when anybody wants to enter the temple. 
Faith in this god, although with
little support in Puranic literature (where Vishnu
really took a female form - Mohini),
is much more based on legends than on Puranic literature. And
legends differ very much depending on a region they come from; their
basis is that Ayyappa is the son of Lord
Shiva who got attracted to Lord
Vishnu, who took a female form known as Mohini.
In Srimad Bhagavatam (Bhagavata Purana) it is written (8.9.9):
"The Supreme Personality of Godhead,
in the form of Mohini, told the demons..."
Legends bring different stories, but they have one thing in common
- Lord Ayyappa is the god for all; he is Unity and Harmony.
He is also known as Bhuthanatha Dharmasastha, Hariharan, Ayyanar and
Manikanta.
Dattatreya
Dattatreya is a Hindu
God who appeared as an incarnation of the Divine
Trinity - Brahma, Vishnu and
Siva. "Datta" means "Given" and this
word is derived from a belief that Divine
Trimurti "gave" Themselves to a sage couple (Atri
and Anasuya). Dattatreya was
a real person, but little is known about him as a historical figure.
He is the son of Atri, hence the name "Atreya."
These are nine primary celestial beings in Vedic astrology (nava = nine; graha = realm).
Surya - the Sun God.
Chandra - also known as Soma, is a lunar deity.
Mangala - god of planet Mars.
Budha - god of Mercury.
Brihaspati - god of Jupiter.
Shukra - god of Venus.
Shani - god of Saturn. Shani is the Lord of Saturday; the word Shani also denotes the seventh day or Saturday in most Indian languages.
Rahu and Ketu
- gods of ascending and descending moon.
Venkateshwara
Venkateshwara - Venkateshwara is the form of Maha Vishnu who preserves the Holy Trinity - Trimurti.
Vishvakarma
Vishvakarma (Vishwabrahmin) is the Hindu presiding deity of all craftsmen and architects, and the divine craftsman of the whole Universe (RV 10.81.3).
