I'm not sure about the first one.
The second one is garlic chives, a herb and the third one
annual Celosia.

First one looks like Amsonia bubrectii,common name Narrow Leaf Blue Star.Phil

Amsonia hubrectii is the first one, I agree, and garlic chives is the second one, and the third does look like an annual Celosia.

Thanks everyone for your quick feedback, appreciate it!

I never thought that the 2nd plant is garlic chives. I grow garlic chives but somehow the flowers are kind of pinkish/purplish, I guess there are many types of garlic chives?

Regular chives (onion chives) have pink flowers. I find garlic chives more aggressive reseeders.

Aggressive is an understatement! Don't let them seed into your garden, and even if you cut the stems when there is still some flower and the seeds are green, don't put them in the compost. You'll be digging little plants for years.
