I believe the first two phots would be zebra plecos? Columbian zebra? L129?
The 3rd one is a synodontis, and I don't think they have numbers but I don't know.
To me the last one looks a bit like a rubberlip but with a leopard coloration, and I don't know enough about those either to have any idea.
But maybe DarkOne knows better than me..

First is an l199, second looks to be either l129 or l270. Third looks like a hoplo catfish. Fourth picture has a spotted rubberlip and another l129/l270.
Last looks like a mustard spot pleco.
