The miracles of Elisha and those of Jesus are sufficiently dissimilar that they are not really genuine coincidences. For example, in the case of Elisha (2 Kings 4:32-35):
32 And when Elisha was come into the house, behold, the child was dead, and laid upon his bed. He went in therefore, and shut the door upon them twain, and prayed unto the LORD. And he went up, and lay upon the child, and put his mouth upon his mouth, and his eyes upon his eyes, and his hands upon his hands: and he stretched himself upon the child; and the flesh of the child waxed warm. Then he returned, and walked in the house to and fro; and went up, and stretched himself upon him: and the child sneezed seven times, and the child opened his eyes.
Compare this to Matthew 9:23-25, to see that there is very little in common between the two miracles (and only the miracle by Elisha was preceded by prayer):
When Jesus arrived at the official's house and saw the flute players and the crowd who were making a commotion, he said, "Go away! The girl is not dead but sleeping." 16 And they ridiculed him. When the crowd was put out, he came and took her by the hand, and the little girl arose.
The passage in 2 Kings 4:32-35 arguably has more in common with Acts 12:10, in which Paul is said to have resuscitated a boy, since both Elisha and Paul are reported to have lain on the child in order to resurrect her or him (and both were followed by talk of food):
And Paul went down, and fell on him, and embracing him said, Trouble not yourselves; for his life is in him.
Whether the rather modest similarities between Acts 12:10 and 2 Kings 4:32-35 were deliberately intended, either by God or by the author of Acts can only be a matter of speculation.
If God intended 2 Kings 4:1-7, 4:38-41, 5:1-14 and 6:5-7 to preview or foreshadow the events described in John 2:1-10, Matthew 14:15-20, Luke 17:11-19 and John 6:19-20 respectively, I could not imagine him making the parallels so obscure that they went unnoticed for so many centuries. Turning water into wine at a wedding hardly evokes turning oil into an abundance; feeding thousands with loaves and fishes hardly evokes turning poison stew into good stew; curing lepers was a quite common claim or achievement in biblical times; making an iron axe head float in somehow unlike walking on water. The similarities are so minor and questionable that I believe the only reasonable conclusion is that the events described for Elisha are neither coincidences nor intended to foreshadow the life of Jesus.
