The first one is twice as MUCH. On first reading it is tempting to say MANY as we are talking about males, which is a countable noun. However, the sentence isn't saying that twice as many males play that sport as females. What it is saying is that 20% of males play that sport, and that is twice as much as the % of women who play it - so, 10% of females play it. So 20% is twice as MUCH as 10%. We could only say that twice as many men play the sport as women if we knew that the total number of men and women in the sample was the same, and we don't know that.
The second sentence is wrong - both grammatically and statistically.
in Cricket and soccer, The percentage of males were 4 times (higher/larger/bigger) then that of female players ,at 10% and 24% respectively.
The percentage of males WAS 4 times (not WERE). 4 times GREATER is better than any of the options you have listed. 24% is not 4 times 10%. And the 'respectively' at the end of the sentence assigns the 10% to males and the 24% to females, which is contrary to the assertion that more males than females play.
The final sentence is clumsy, but regardless, you could probably use either FOR or OF here. Another way to say it is, 'For basketball, the percentage of males and females was equal, at 7%.'
