The recent innings of 277 by Tamil Nadu's Narayan Jagadeesan, against Arunachal Pradesh in Bengaluru on November 21, elbowed the 268 of Alistair Brown (for Surrey vs Glamorgan at The Oval in 2002) down to second place on this list. It was Jagadeesan's fifth successive century in List A matches, another record.
We managed to track down a photograph of the East African squad arriving at Edgbaston in Birmingham for one of their World Cup matches in 1975 (they lost all three fairly comfortably, to New Zealand, England and India. The picture shows the team's blazers fairly well. The man on the extreme right is Don Pringle, the father of the later England allrounder Derek. I asked him what he remembered of the team's exploits: "I don't remember the blazer at all, and certainly can't recall a flag," said Derek. "The blazer badge looks like it might depict the national birds of Kenya, Uganda, Tanzania and Zambia around an outline of Africa."
The highest stand in Tests by a pair of one-cap wonders is a modest 53, by Derbyshire's William Chatterton and Victor Barton of Hampshire, for England against South Africa in Cape Town in 1891-92. The Cape Times recorded that "Enthusiastic cheers followed the downfall of the Derbyshire crack" (Chatterton) for 48, while Barton "had shown some magnificent hitting, having slashed up 23 in 25 minutes". That was the only Test of what was essentially a private tour, and neither man came terribly close to England selection again. The second-highest - and the only other stand of more than 24 - is 49 by Takudzwanashe Kaitano and Dion Myers for Zimbabwe against Bangladesh in Harare in July 2021. It's quite likely that one or both of them will play another Test (Myers is still only 20), which would remove them from this list.

You're right that the Czech Republic left-hander Sabawoon Davizi, who was born in Afghanistan, has scored three centuries in T20I - 101 against Malta in Marsa in his second such match in October 2019; 115 not out against Bulgaria, also in Marsa, in May 2022; and 111 not out against Austria at home in Vinor in July 2022.
My first thought was that it might be Shahid Afridi's wife, Nadia… but actually it is the Pakistan women's player Nida Dar. She apparently earned the nickname as her attacking play reminded some of Afridi's explosive exploits.
