Can I uninstall or disable pre installed apps on my moto e ?

[AC Question]

My moto e came with loads of preloaded stuff ...half of it I have no idea what it is and don't use it but when I try to disable or uninstall any preloaded I get a warning message that other things will not work properly if I continue.
I need space on my phone - even more so now I have installed the lollipop update
Any help greatly appreciated - I am a techno numpty
