Hi and welcome to KnittingHelp!
If you click on the 14th photo down in this project, it looks like a singe repeat of the chart. You can clearly see the tip and just about count the sts.
When you have both brackets [ ] and parentheses () or even asterisks ** start at the innermost set and work out.
For directions like 1k [yo 1ktb 1p ( 1k 1ptb 1k) 5 times] knit to the end, repeat the (1k, pfb, 1k) 5 times.
If it then said to repeat the directions in brackets x times, you would start at the yo, 1kfb, 1p, and work through to the ending bracket including a repeat of the parentheses 5x. Do this for x times. At least at this point in the pattern there are no repeats of the instructions within the brackets [ ].
This is all explained with clearer examples in the following video. The instructions for repeats start at about 3:00 and especially after about 6:45. The symbols used may be different but the idea is the same.
