First; welcome to R2R! Thanks for signing up.
The stocking list does seem a bit heavy to me for a 60gal. The lion will need most of the space for itself; the puffer and wrasse will also needs a good bit of room as well. Chromis (I assume that's what you meant?) and cardinals will hang out in the water column as well, adding even more congestion...
And yeah; that's without factoring in any resulting aggression that any given fish will have. You could get lucky and have everyone be docile and play well with each other, but that would be unlikely, IMHO.
It's hard to pick just some fish, isn't it?!? :-)
