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.
