Which techniques would those be? I recall him imitating a weaker mediocre version of Roshi's Kamehameha at the beginning of the series. At the 21st tournament, Goku is unable to replicate the Drunken Fist style, presumably due to a lack of indulgence with alcohol which is an integral part of grasping the unpredictable motions of such an inebriated state, so he resorts to an improvised Mad Dog stance instead. Admittedly, he does grasp the Afterimage shortly after Jackie Chun used it. I think the next incident of him "copying" a technique is with Tenshinhan's Shiyouken, though he didn't sprout tangible limbs from his back like Tenshinhan did; it was a rapidly repeating motion of the arms to give the illusion of having extra appendages which he actually acquired from King Chappa. Following this, the ability to sense Ki required years of meditative training despite having witnessed Popo use it. To put this in perspective, Vegeta learned how to sense Ki not too long after having battled with Goku and the others. He does show knowledge of the Taiyoken and Kienzan, but this is years after he first witnessed these techniques. It's not indicative of having grasped abilities any better than Tenshinhan has. Granted, I overlooked the time span in which Tenshinhan learned the Mafuba. Regarding King Kai -- we're not aware of any of the particulars concerning the training with others. Given the fact that Piccolo wasn't aware of the Spirit Bomb's existence, though, it's likely neither he or the others were intended to learn them by King Kai.
Roshi was revived usign the Earth's Dragonballs, but the same doesn't hold true for either Tenshinhan or Piccolo. They were revived both times using the Namekian Dragonballs which we know do not have a limit in the amount of times they can revive someone. As for the non-existence of the future Dragonballs, the group could always bring their version and use them in the future. Nothing is preventing them from doing so as far as we know. Goku also has in the past been willing to entrust the fate of the world to others, even when they were initially uncertain of the prospect. This occasion should be no different, especially if they're volunteering to do so.
The Micro Band has yet to be used for the same reason any other retro device or concept hasn't in spite of their potential usefulness to the present conflict. It's why Akkuman was never called upon to kill the Saiyans, Freeza or the cyborgs with his technique. And the reason why I cited Kaioshin instead of Beerus is because of his teleportation ability and the possible applications with it. Beerus can't teleport.
Goku mimic a weakened Kamehameha before he had any real training since his grandfather died years ago. Tien by the time he copied the Kamehameha was older and was more well-trained. Goku couldn't copy the Drunken Fist specifically because he never got drunk before, so he created a counter, Mad Dog
and Crazy Monkey. He actually used King Chappa Eight-Arm Technique against Tien, not the Four Witches. I would also argue that Goku began to sense ki as soon as the 22nd Tournament. He knew that Tien was more powerful than he let on, he felt Master Roshi die to King Piccolo, and he sensed where Piccolo was after drinking the Ultra Divine Water. His training with Kami was only fine tuning it, which works since he has one of the best ki sense in the series. Also, Goku never actually saw Krillin use the Kienzan. The closest would be Freeza's tracing version. He also did use the Solar Flare better than Tien at the 23rd Tournament. He kept the Solar Flare going for several minutes after using it and could turn it off at any time, instead of the quick flash. I should also point out that Piccolo was only with King Kai for a couple of days before he was revived and went to Namek, while Tien was there for a three fourths of a year.
Piccolo needed the Namekian Dragon Balls according to Goku in Super when Frieza killed him. And why would they bring their version to the future. No one has never suggested that, not even once. Plus, if they do that, they would have to return to Trunks' time in a year's time to get them and we don't even know if the Dragon Balls can be used that way. Goku is willing to entrust the future to others, true. Letting them die when he can do something isn't one of them.
The Supreme Kai isn't going to the future. He wasn't even with them when they went back to Earth.

That doesn't imply Zamasu is near Beerus's level unless you want to believe now Current Arc SSJ2 Goku is far above Champa Arc SSJB Goku.
He can someday according to Goku, and Future Zamasu is older than Present Zamasu who was able to trade blows with Super Saiyan God Super Saiyan Goku.
