Omniscient

the capacity to know everything infinitely, or at least everything that can be known about a character including thoughts, feelings, life and the universe, etc.

Hebrews 4:12-13

For the word of God is living and powerful, and sharper than any two-edged sword, piercing even to the division of soul and spirit, and of joints and marrow, and is a discerner of the thoughts and intents of the heart. And there is no creature hidden from His sight, but all things are naked and open to the eyes of Him to whom we must give account.

Omnipotent

A deity is able to do anything that it chooses to do. A deity is able to do anything that is in accord with its own nature (thus, for instance, if it is a logical consequence of a deity’s nature that what it speaks is truth, then it is not able to lie. Hold that it is part of a deity’s nature to be consistent and that it would be inconsistent for said deity to go against its own laws unless there was a reason to do so.

A deity is able to do anything that corresponds with its omniscience and therefore with its world plan. A deity is able to do absolutely anything, even the logically impossible.

Omnipresent

The property of being present everywhere. This attribute (being present everywhere) seems to be the only one that Jesus doesn’t demonstrate after taking on human flesh. Taking on physicality means He can only be in one location at a time. Even now he has physicality in His glorified body, sitting at the right hand of the Father. Yet, all the fullness of Deity dwells in bodily form (Doctrine: Hypostatic Union). Jesus had  two natures and therefore could claim the attribute of Omnipresence. 

Colossians 2:9

For in Him all the fullness of Deity dwells in bodily form

John 17:5

And now, Father, glorify me in your presence with the glory I had with you before the world began.
