Are the Gods created after the Supreme consciousness created the Universe present in Materialistic forms? Ex. Brahma, Vishnu, Shiva, Saraswati, Lakshmi, Parvati, Indra, etc.
Yes, as we say God is omnipresent. Refer CC Ādi 2.49
kāraṇābdhi-garbhodaka-kṣīrodaka-śāyī māyā-dvāre sṛṣṭi kare, tāte saba māyī
“The Kāraṇodakaśāyī, Garbhodakaśāyī and Kṣīrodakaśāyī forms of Nārāyaṇa all create in cooperation with the material energy. In this way They are attached to māyā.

The mind, intellect, ego, ether, air, fire, water, and earth are the eight fold division of My material energy. (See also 13.05) (7.04)
The material Nature or matter is My lower Nature. My other higher Nature is the Spirit by which this entire universe is sustained, O Arjuna. (7.05)
Know that three modes of material Nature goodness, passion, and ignorance also emanate from Me. I am not dependent on, or affected by, the modes of material Nature; but the modes of material Nature are dependent on Me. (See also 9.04 and 9.05) (7.12)
All manifestations come out of the primary material Nature during the creative cycle, and they merge into the primary material Nature during the destructive cycle.
