Once you have made %uptime.top4.times & %uptime.top4.nicks you can use
1st place is $gettok(%uptime.top4.nicks,1,32) with a time of $gettok(%uptime.top4.times,1,32)
2nd place is $gettok(%uptime.top4.nicks,2,32) with a time of $gettok(%uptime.top4.times,2,32) seconds
3rd place is $gettok(%uptime.top4.nicks,3,32) with a time of $gettok(%uptime.top4.times,3,32) seconds
4th place is $gettok(%uptime.top4.nicks,4,32) with a time of $gettok(%uptime.top4.times,4,32) seconds

if thats to hard try

var %tmp = $1- | tokenize 32 %uptime.top4.nicks %uptime.top4.times
1st place is $1with a time of $5 seconds
2nd place is $2with a time of $6 seconds
3rd place is $3with a time of $7 seconds
4th place is $4with a time of $8 seconds
tokenize 32 %tmp

* The var & tokenize at the begining saves the $1- values then replaces $1- with the 4 names then there 4 times
* the tokenize at the end returns the old $1- back to what they were
