>> Can stregex match an expression multiple times?

Not that I am aware of. You have to repeat the search string twice (note I added "[^0-9]*" to the end of the regex).

nRepeats = 2
time_regex1 = '([01][0-9]|2[0-3]):([0-5][0-9]):([0-5][0-9])[^0-9]*'
time_regex = strjoin(replicate(time_regex1, nRepeats))

timeStr = '10:21:41 - 11:32:00'
print, stregex(timeStr, time_regex, /SUBEXP, /EXTRACT)

-------------------
If you have no way of knowing how many times you will have, you can make the whole expression optional.

nRepeats = 5
time_regex1 = '(([01][0-9]|2[0-3]):([0-5][0-9]):([0-5][0-9])[^0-9]*)?'
time_regex = strjoin(replicate(time_regex1, nRepeats))

timeStr = '10:21:41 - 11:32:00'
result = stregex(timeStr, time_regex, /SUBEXP, /EXTRACT)
for i = 0, 12 do print, result[i]

10:21:41 - 11:32:00
10:21:41 -
10
21
41
11:32:00
11
32
00
