Hello Blondee

.... Welcome to the forum
You made great choices with beautiful blooming plants

I love hibiscus my self.
I guess my first question is,, did you dig the holes deep and wide enough and fill in with a rich soil? Rich soil meaning a good organic mix with peat moss maybe even some bone meal?
You have to water it probably daily until it's established then it will take it's own and grow.
It takes time for roots to establish in a new environment and new soil. As long as you see green and the stock isn't soft you should be fine, be patient. Every 3rd watering I would add a some plant food whether it's miracle grow or one of your choice( you can call your local nursery and they will recommend you one as well)
You didn't mention how long ago you planted, weeks or days, so it's hard to say whether they are yet established.
Since you already see new growth in most of them I wouldn't worry too much, :wink:
You didn't say what
growing zone you're in,, I'm in Texas so both the hibiscus and
rose of sharon are hardy here and come back every year, and get bigger and better with each year.
