Oh finally some questions I can answer haha.
1 - Yamcha should most likely win. Not only was he confident against a Goku that trained for 3 years, having already seen Goku going all out in the Baba tournament, but he was on the same level as Kuririn, who got Goku to reveal more of his powers to be defeated. Roshi and co. were surprised with the way Goku handled Chappa, meaning that level from Goku already exceeded the level 3 years prior, and Kuririn matched initially, blow for blow, a Goku that had no reason to go easier on him than vs Chappa, until Goku leveld up. Tao would be embarassed.
2 - That's somewhat hard to answer. We know that Videl was stronger than her father, who himself couldn't take bullet shots and was thus way weaker than start of Dragon Ball Goku. Videl has some chi control, but we saw that a bullet still injured her knee. Since Ranfan could damage Namu, even accounting for him being off guard, and dodge an attack from a serious Namu, I'd still say Ranfan gets this. Strange to think about it, maybe just saying Videl sounds more sensible, but looking at these feats, I'd be inclined to give it to Ranfan.
3 - Assistant Black still had some, although little, confidence in see Goku's strength before jumping to his battle armor, and withstood a punch to the gut, from a Goku many time superior than the one who easily defeated Blue, so he should be considerably stronger. Blue has got his telekinesis, but Black arguably knowing this, should be able to avoid it.
4 - Is Master Shen, Tsuru Sennin? If so, Tsuru gets it easily. He was only said to be surpassed once Tenshinhan fought Roshi, meaning he's logically above Yamcha, being then by scaling way above that Goku.
5 - Hmm depends on the multiplier. Still, I don't have a high SSJ amp for that time period, and adding the way base Vegetto was portrayed in the anime, would make me bet on Vegetto taking Gohan even without the necessity to transform.
6 - Guld is deemed as weak by Kuririn, but may be just a general comparison to the whole Ginyu Force. We know that the powers Gohan and Kuririn had, both >> 10,000 were too fast for him to even react to. I wouldn't say he's very low, like 2,000 or anything, but maybe 6,000 or so sounds enough. Nappa had a real toughness and was able to go toe to toe with base Goku once calming down. Gotta give it to him.
7 - V-Jump estimates Kuririn as 75,000 vs Freeza. I used to give him more credit since Vegeta considered him valuable vs Freeza, but I think team battles don't always follow a specific pattern, so I, these days, adopt this figure for him. Having said that, and considering Vegeta said his power was still rising, I think he got up to 100,000 or so in the Mecha Arc. Maybe he even equaled or surpassed Ginyu, I dunno. Still tho, I give it to Ginyu.
8 - This one I don't know, I don't remember which power Paragus was read at. If it's 2,800 or above, then he wins.
9 - I don't remember if Vegeta's power was specified there, but in the Toei special, Bardock was given as near 10,000 iirc and no mention of him surpassing King Vegeta was made. Vegeta stated he surpassed his father as a kid still, though I don't know how kid he was, so tough to answer. Assuming it's more or less from that time period, Vegeta could have a 12,000 or so BP, way above normal Goku's.
10 - I don't really remember what Pan accomplished on that movie, tbh. My memory of it is already foggy.
