Please enlighten me about DSD/SACD, DVD-A or DTS- confused

[BaTou069]

Hey Folks,
 
I'm relatively new to HQ digital audio, just received my first DAC ever (FiiO E18)
 
I already downloaded different stuff in the past, somewhere on my hard disk: music in SACD and DSD, dts CD's, multichannel wav...
I'm a bit confused about what is what and how is it played.
Some are .iso files, other .bin (both images I guess), others are .wav files and others .dts files
What is what? What is lossy and what lossless? Can I play an image of a SACD or DSD on my pc with a proper DAC?
If not, how can I listen to the music?
 
Thanks

iso, wav, bin   - they are all lossless.
other lossless formats:     flac,   ape
 
regarding high res:  SACD,  DSD...          I like CD better,   44.1k Hz,  16bit.     SACD/DSD sounds smooth, but I perceive it as loss of information instead of realism.
