Level 0: absolutism(?)(word may be changed). Nothing is relative, there is always an objective perspective, and all other perspectives are wrong
Level 1: package-deal relativism. Perspectives are relative to the various religions/worldviews/etc. However, only those that are "properly packaged" are considered valid. For example: Christianity, Islam, (modern western) atheism, Hinduism, Buddhism, Libertarianism, Conservatism, Fascism, Nazism, Liberalism, Marxism, Jainism, Shintoism, hellenic polytheism, Satanism, progressivism etc etc. they're all worldviews that have a specific set of beliefs, attitudes and perspectives. In (what I call) package-deal relativism, each of these is considered valid, however it is invalid to create hybrids. For example, Christo-Paganism, or other hybrids are not accepted, unless those are accepted as "valid packages" (interpretations on which packages are valid may differ significantly). However, as a general rule, syncretism, eclecticism, hybrids etc are considered invalid in package-deal relativism.
Level 2: modular relativism. At this level, it is possible to "pick and choose" elements from different religions/worldviews and develop your own worldview. For example, you can fast during the month of Ramadan, celebrate Christmas on December 25th, believe in the Hindu Yugas (cosmological eras) and be a henotheistic Satanist all at the same time. However, in modular relativism, each "module" (i.e. part of a religion/worldview) must remain unaltered. For example, you cannot celebrate Christmas on February 22nd, you cannot modify the rules of Ramadan fasting such as you can drink water during the daytime hours, or that we are in Dvapara Yuga instead of Kali Yuga. Modular relativism allows eclecticism, syncretism, hybrids etc as long as each "module" remains faithful to its original meaning and characteristics.
Level 3: hyper-modular relativism. At this level, it's possible to modify each module as one wishes, allowing full freedom over one's own worldview. Want to celebrate Christmas on February 22nd? Sure, go ahead! Want to drink water (but not eat food) during the day during Ramadan? Sure! Do you think we're currently in Dvapara Yuga, and that the Kali Yuga (the most decadent era) will start in 2100 and will last until 3100? Sure, sure! At this level, there's full of freedom, the possibilities are endless, especially for "crazy" stuff (in a positive/interesting way). Maybe at this level there could be some interesting, useful perspectives that one can use (chaos magick sees beliefs as tools, and this level of relativism is the deepest and most powerful in magickal terms).
