How many angels escorted Jesus up and down Jacob's Ladder?

Ignoring the Creation of the Universe, the Son of God has ascended and descended four times so far, with a fifth to come. Just out of curiosity, it's interesting to consider His "posse", the angels which accompanied His journeys...

•        When He came to earth from Heaven, in (probably the spring of) 4 B.C.,  we know from Luke 2:8-13 that there were a multitude of angels, which presumably means more than two...

And in the same region there were shepherds out in the field, keeping watch over their flock by night. And an angel of the Lord appeared to them, and the glory of the Lord shone around them, and they were filled with great fear. And the angel said to them, “Fear not, for behold, I bring you good news of great joy that will be for all the people. For unto you is born this day in the city of David a Savior, who is Christ the Lord. And this will be a sign for you: you will find a Baby wrapped in swaddling cloths and lying in a manger.” And suddenly there was with the angel a multitude of the heavenly host praising God and saying,“Glory to God in the highest, and on earth peace among those with whom He is pleased!"

• Upon His crucifixion, He descended to Hell, taking the sins of mankind with Him to deposit and free us from God's condemnation. To my examination of Scripture, I don't see any mention from any of the four Gospel writers of any angels who traveled with Him - and it wouldn't make sense for angels to have traveled to Hell anyway, so this almost certainly was a journey He took alone - without angelic backup, without God alongside Him (because He carried sin), without anyone except His Own Strength.
• In Matthew 28:2, "an angel of the Lord descended from heaven and came and rolled back the stone and sat on it.". Luke, on the other hand, says in his gospel that "two men stood by them in dazzling apparel" (Luke 24:4). Mark 16:5 says it was one angel; John 20:12 says it was "two angels in white.". So...what, do we average them? One and a half angels? I think it's more likely that Levi Matthew and John Mark both missed an angel, rather than John and Peter (the eyes of Luke) having seen double. But we can safely assume that there were either one or two angels accompanying Christ upon His ascension back to earth from Hell.
• Finally, when He ascended back to Heaven, Luke was the only one who told us about the scene surrounding His departure: "And while they were gazing into heaven as he went, behold, two men stood by them in white robes, and said, 'Men of Galilee, why do you stand looking into heaven?'" (Acts 1:10-11).  This also makes me think it was two angels in the previous move, but that's immaterial. 

So, there were a multitude of angels heralding His arrival from Heaven, but never more than two around when He moved from place to place in this realm, including Hell. It is ONLY when God chose to come down from Heaven that it was such a big deal that a "Heavenly host" accompanied and celebrated the occasion - the rest was just part of the business trip, it seems.

What do we expect will happen the next time He chooses to come down here? Well, we already know what'll happen: Christ Himself told us on the Mount of Olives, in Matthew 24:30-31 →

"Then will appear in Heaven the sign of the Son of Man, and then all the tribes of the earth will mourn, and they will see the Son of Man coming on the clouds of Heaven with power and great glory. And He will send out His angels with a loud trumpet call, and they will gather His elect from the four winds, from one end of Heaven to the other."

"He will send out His angels." Not angel, singular; angels, plural. And not just a couple - "they will gather His elect from the four winds, from one end of heaven to the other." That's going to take a whole lotta angels!

When the time comes, and it's coming very, very soon, He won't be subtle. His sign will appear in Heaven, and "all the tribes of the earth will see the Son of Man coming with power and great glory...with a loud trumpet call." You will not be able to mistake the Second Coming of Christ for anything else. So if you hear or see someone who appears to be the second coming of Christ, or who claims to be the Christ...there shouldn't be ANY DOUBT in your mind. 

And if you're truly saved, you won't even have to make that evaluation, because the first thing you'll have to notify you of His Arrival will be your own departure.
