Figure 8's can live in freshwater........................... for a while. Sooner or later the fishes immune system will be suppressed though and its only a matter of time before they come down with something. As for the other fishes
The gost knife will reach a max size of 20" ----> NOT SUITABLE FOR A 29 GALLON!
The Pleco will get 18" if its the common pleco -------> Also not suitable
Although fine now, the lobster will become somewhat preditory. If it corners a fish, or surprises one during the night, bam, the fish is gone.
I know you don't want people to point out things wrong with your tank, but take it as constructive critisim... we are only trying to help you avoid the headaches of bad decisions and inappropriate stocking. Your 5 gallon is also overstocked, as tetras need a bit more swimming room than a gallon a piece. I'd look into guppies for that tank or dwarf platys. Put the serpaes in your new tank, take back the black ghost and the lobster and possibly the pleco.
