I personally like to look at the 1 day, 1 hour, 15 minute and 5 minute charts before I trade for a day. The daily is just at the start and a mental reminder of what the market has been doing over a longer time, if all the trends align, I feel a lot more confident in my trades, but it's not necessary for the daily to align. The others, the longer time frames often show where the bigger movements actually are, and the shorter times are useful to read where to place your entry. At least that's been my way of using them so far. So for example, I'll check the daily, and if it looks like I'm approaching a trend low or high, I might decide to avoid that day entirely, but for the trends that I want to trade on the 5 minute chart, I'll look at the hourly to mark highs and lows at first, usually by marking the wick if it's a big candle, then the 15 to try and dial the movement in, then to check the trend at my time, after all that I move to the 5 for quicker small trades, but only if the trend looks strong and healthy. I've noticed it's for the best if I avoid the 1 minute. Others I've heard have good success with it.
