As we have seen here https://abn397.wordpress.com/2019/10/20/umesh-yadavs-batting-record/
The fastest score of 25+ was 31/10 balls, with a strike rate of 310.00
For 50+, it is 54/25 balls and 216.00
For 100+, it is 110*/58 balls and 189.65
Now let use see about the highest strike rates for innings lasting for one to six balls.
There is no record of anyone scoring more than a zero off zero balls, though it may be theoretically possible under some obscure rule.
Here you have only 0* and 0, the latter being diamond ducks.
Now for 1-ball innings:
There is only one such innings involving a six, and it is fittingly by Jayasuriya with an SR of 600. Next is Ishant Sharma with 5 (a single plus 4 overthrows) and 500. Then there are those who scored a 4 or 3 off one ball. Ishant Sharma appears again. At least half of the batsmen here are tailenders. Even the famous batsman CS Martin has scored 4 off one ball! So has NM Lyon.
2-ball innings:
There are four batsmen (all tailenders) who have made 7 off two balls. They would have made a 6 and a single, apart from Muralitharan who made a 4 and a 3. Then there are 6s and 5s. Here we do not meet a recognized batsman until Sir Richard Hadlee (?) and AL Logie. The only current players are Wafadar of Afghanistan and India’s Mohammed Shami.
3-ball innings:
The highest off 3 balls is 12* by Misbah, including two sixes and a dot. Murali has 6,4 and dot while Shami has two fours and a two. Others have made 6 runs with one four. Muralitharan appears three times here. The proportion of recognized batsmen is more here, including current players Mushfiqur and Malan along with Shami.
4-ball innings:
The maximum here is 12, either by 3 fours (de Villiers and Warner) or 2 sixes (Henry). Warner, Henry and M Marsh represent the current players.
5-ball innings:
The best here is by Southee (another expert tailend slogger) with 3 sixes in his 20. He has also made 13 to be in second place with Pietersen.
6-ball innings:
The highest here is 17* which is less than the 20 in 5 balls. Ntini made his 16* with 4 fours. KMA Paul’s 12 included 3 fours.
Having come so far, we can also see
Most successive sixes:

Kapil’s 4 successive sixes came when averting the follow-on with No 11 at the other end. The No 11 (Hirwani) was out just after the follow-on was averted. There are numerous current players here (such as Southee) besides old-timers such as Hammond.
And finally,
Most successive fours:

All 6 balls by Jayasuriya, Sarwan and Gayle (although Sarwan had a no-ball interspersed after 4 sixes. DW Hookes hit 5 fours on his debut, which came in the Centenary Test of 1977. So did RE Redmond, a staple of quiz questions.
