Let me ask you a question, as I think you are all over the place on this topic.
Literal or figurative?
Two Olive Trees
Two Candle Sticks (lampstands is the proper meaning!)
Two witnesses
I'm just looking to see if you can approach the text with the right mindset for now.

Isaiah 13:2-4
Lift ye up a banner upon the high mountain, exalt the voice unto them, shake the hand, that they may go into the gates of the nobles.
I have commanded my sanctified ones, I have also called my mighty ones for mine anger, even them that rejoice in my highness.
The noise of a multitude in the mountains, like as of a great people; a tumultuous noise of the kingdoms of nations gathered together: the Lord of hosts mustereth the host of the battle
Revelation 14:1
And I looked, and, lo, a Lamb stood on the mount Sion, and with him an hundred forty and four thousand, having his Father's name written in their foreheads.
In Isaiah 13 his sanctified ones are His Two Witnesses, and his mighty ones are his remnant.
Isaiah 25:6-8
And in this mountain shall the Lord of hosts make unto all people a feast of fat things, a feast of wines on the lees, of fat things full of marrow, of wines on the lees well refined.
And he will destroy in this mountain the face of the covering cast over all people, and the vail that is spread over all nations.
He will swallow up death in victory; and the Lord God will wipe away tears from off all faces; and the rebuke of his people shall he take away from off all the earth: for the Lord hath spoken it.
Isaiah 43:7-10
everyone who is called by my name,
whom I created for my glory,
whom I formed and made.”
Lead out those who have eyes but are blind,
who have ears but are deaf.
All the nations gather together
and the peoples assemble.
Which of their gods foretold this
and proclaimed to us the former things?
Let them bring in their witnesses to prove they were right,
so that others may hear and say, “It is true.”
“You are my witnesses,” declares the Lord,
“and my servant whom I have chosen,
so that you may know and believe me
and understand that I am he.
Before me no god was formed,
nor will there be one after me.
The Lord is saying let "them" bring in their "witnesses" to prove they were right.
Their "witnesses" being The Two Witnesses of Revelation and "them" being the ones who stand on mount Zion with the Lamb.
In Zechariah 4,is Zerubbabel literally coming to finish it?or was the Lord speaking of his remnant?
Look what happens to Joshua in the chapter before Zechariah 4.
Zechariah 3
And he shewed me Joshua the high priest standing before the angel of the Lord, and Satan standing at his right hand to resist him.
And the Lord said unto Satan, The Lord rebuke thee, O Satan; even the Lord that hath chosen Jerusalem rebuke thee: is not this a brand plucked out of the fire?
Now Joshua was clothed with filthy garments, and stood before the angel.
And he answered and spake unto those that stood before him, saying, Take away the filthy garments from him. And unto him he said, Behold, I have caused thine iniquity to pass from thee, and I will clothe thee with change of raiment.
And I said, Let them set a fair mitre upon his head. So they set a fair mitre upon his head, and clothed him with garments. And the angel of the Lord stood by.
And the angel of the Lord protested unto Joshua, saying,
Thus saith the Lord of hosts; If thou wilt walk in my ways, and if thou wilt keep my charge, then thou shalt also judge my house, and shalt also keep my courts, and I will give thee places to walk among these that stand by.(his two anointed ones who are standing by the Lord of the whole earth)
Hear now, O Joshua the high priest, thou, and thy fellows that sit before thee: for they are men wondered at: for, behold, I will bring forth my servant the Branch.
For behold the stone that I have laid before Joshua; upon one stone shall be seven eyes: behold, I will engrave the graving thereof, saith the Lord of hosts, and I will remove the iniquity of that land in one day.
In that day, saith the Lord of hosts, shall ye call every man his neighbour under the vine and under the fig tree.
