120g Reef Stocking

Take this 'as is'
I'm no expert, but I've learned a few things this last couple years

When I first started my tank I asked a similar question, but shouldn't have
There's so much info on the web if you look for it
Research each fish you like and check their compatability against each other
Use this tool for reference

As far as your list goes, the first things I see as bad are;
Lionfish and your current stock
CBB and a new tank
Trigger and SPS, plus a tank not large enough
Leopard wrasses are sensitive, so wait 6 months or a year for your tank to mature and you still have to be careful
Cleaner wrasses need natural food ie parasites, so I'd suggest a no go
Chromis are jerks to each other so good luck with that. And they're food for the lion

Check out liveaquaria for lots of info, and do some cross-research about the fish you 'must have' before you make any decisions

Basically, I suggest you decide whether you want a 'gentle', 'active', or 'aggressive' tank before you buy any more fish as what's on your list is not a good mix
