The top 3 look like Neon Wrasse Halichoeres Melanurus but it's alway hard to tell but it's in that family, Halichoere.
The 4 picture looks like it's in the Macropharyngodon family, maybe a Potter's wrasse or something like that.
The last photo you got me.
You probably want to do a search on the web for a site that list Hawaiin fish as I'm sure these are probably common and listed there.
