Distances are long and time is short in your case... Unless you fly... Even then you are asking a lot.
If you fly into Manado and out if Makassar(aka ujang pandang), its easier but Komodo still not possible... Or visa versa
From Manado to Togeans is 2 full days of travel by bus/private taxi plus and boat ferry... From Togeans to Toraja is another 2 days, and Toraja to Makassar is 12hours by bus...
Suggest you do only Toraja and Togeans and fly in and out of Ujang . This would give you a week in Togeans and 3-4 days in Toraja..... Or similar
If you really must do one more place, Bira in the south is a nice change
Some depends on what you want to see though... Snorkeling /diving is better IMO in Manado then Togeans, but Togeans is very idyllic.. Big currents in both Manado and Komodo, so be aware.. Komodo divibg is excellent
