These above all refer to an appearance, so I will omit these, because they do not even come close to mentioning seeing His face. Which leaves us with these below.
Gen.32:30
"And Jacob called the name of the place Peniel: for I have seen God face to face, and my life is preserved."
Ex.33:11
"And the Lord spake to Moses face to face, as a man speaketh to his friend."

Ezek.20:35
"And I will bring you into the wilderness of the people, and there will I plead with you face to face."
Gen.32:30~~~ If you read the whole chapter, you would notice at the beginning where it says angels of the Lord, following on, in his dreams he wrestles with a man. Which gives him the mental vision of seeing God. Unless you prefer to think that he really did wrestle with God in the flesh in Genesis?
.
Ex.33:11~~~Ex.33:23~~~ These two should explain what it meant to see God 'face to face'. How can he not see Gods face, but see it at the same time. Again, read the whole chapter. Just because it says face to face, doesn't mean that they were standing looking into each others face, and if you were to read the whole chapter, you could see that. Even metaphorically speaking, you still have to say that if he seen His face it would be a contradiction within itself.
.
Num.14:14~~~ Seems you omitted the rest of this verse, let me state the whole thing, and then I will explain.
14: and they will tell the inhabitants of this land. They have heard that thou, O LORD, art in the midst of this people; for thou, O LORD, art seen face to face, and thy cloud stands over them and thou goest before them, in a pillar of cloud by day and in a pillar of fire by night.
He appears to them face to face (figuratively). He actually appeared to them as a cloud by day, and a fire by night. So that they know that He is there, so they are seeing 'face to face'.
.
Dt.5:4~~~ You see where it says out of the midst of fire? That means he appeared as a midst of fire, not by showing His face.
.
Dt.34:10~~~This is speaking of Moses. Now if you can explain face to face, meaning anything other than a close personal relationship after reading the following passages from Exodus 33, please let me know.
12: Moses said to the LORD, "See, thou sayest to me, `Bring up this people'; but thou hast not let me know whom thou wilt send with me. Yet thou hast said, `I know you by name, and you have also found favor in my sight.'
13: Now therefore, I pray thee, if I have found favor in thy sight, show me now thy ways, that I may know thee and find favor in thy sight. Consider too that this nation is thy people."
14: And he said, "My presence will go with you, and I will give you rest."
15: And he said to him, "If thy presence will not go with me, do not carry us up from here.
16: For how shall it be known that I have found favor in thy sight, I and thy people? Is it not in thy going with us, so that we are distinct, I and thy people, from all other people that are upon the face of the earth?"
17: And the LORD said to Moses, "This very thing that you have spoken I will do; for you have found favor in my sight, and I know you by name."
18: Moses said, "I pray thee, show me thy glory."
19: And he said, "I will make all my goodness pass before you, and will proclaim before you my name `The LORD'; and I will be gracious to whom I will be gracious, and will show mercy on whom I will show mercy.
20: But," he said, "you cannot see my face; for man shall not see me and live."
21: And the LORD said, "Behold, there is a place by me where you shall stand upon the rock;
22: and while my glory passes by I will put you in a cleft of the rock, and I will cover you with my hand until I have passed by;
23: then I will take away my hand, and you shall see my back; but my face shall not be seen."
.
Ezek 20:35~~~ ties into the verses following it, which I explained above. (In the wilderness)
Angel
The chapter repeats the fact that it happens at night, or in a dream, and obviously when we dream we are not physically wresting with someone, at least not in mine.
