Hi Shane, some suggestions.
2 severum -- keep, and maybe even add more if you like them so much? Have you seen red-spot severums?
2 red zebra -- rehome. will be happier in a proper african tank.
1 yellow johannis -- rehome
4 Demasoni -- rehome
15 krib -- keep if you like them, although this is a lot of kribs!
10 bristle nose -- again keep if you like, but this is a lot! They will be making quite a mess as plecos are waste machines
7 electric yellow -- rehome
8 tiger barbs -- keep if you like, although I had tiger barbs with american cichlids and found what when the cichlids got bigger the barbs couldn't compete well enough for food and eventually died off.
Some cichlids which may work for your tank, depending on whether you keep the kribs, bristlenoses and barbs are Oscars, Red-head cichlids, t-bars, convicts, Jack dempsey or electric blue jack dempsey.
Also consider Hoplo Catfish (these are great! so active and friendly!), silver dollars, or even a school of clown loaches would be impressive in a tank this size. All the fish I have suggested work well in your water pH and with Severums.
Also Severums are a great fish. I just sold my 3 red-spots after 3 years, they were so awesome.
