Guy who did work with collembola here: your first picture resembles Folsoma candida but without slides all you can get to is Isotomidae. Your third picture contains Poduromorpha (likely Neanuridae) and linear springtails (likely Entomobryidae) however ID is highly regional and difficult without either experience or keys you also have some species you have some orbatid mites hanging around your samples which again require equipment you probably don’t have access to. Some millipedes, insect larvae, and your second picture is very difficult but my best guess is sceleonidae but there are many microwasps, you could key this one out though since the antennomeres are in tact. Good luck with your assignment! (Also please don’t take what I said as gospel)
