Pic 2: definitely looks like filamentous diatoms and 3 is diatoms as well. I cant really see pic 1 clearly. Is it a new tank? They usually subside on its own after sometime (1-2months). But they turn green then back to brown when placed in H2O2. You can do the One-Two Punch to remove it , but it will come back. They feed off silicates and it is possible to have water that has high silicates as well.
I would also drop your light to 8hrs a day or less. Also crank up your CO2. Supposedly Ottos and amanos will eat it, but Ive had both and neither put a dent in mine. I dropped my lights, manually removed, One-two punched and eventually went away (mostly)..
