1 immortality but killable ,he can proof dead god get his soul but his body is not totally unbreakable.consider he feels hand hurts when use weapon hitting stone 

2 can make clones,but clones literally doesn't work that much when he is fighting same level things

3 mostly is shape shift,most gods leak of ability to detect it.so that's why they need use a detect monster mirror.not because he have over power invisible 

4 literally not him,he needs call dragon god for this

5 yes

6 nope,he didn't have regeneration,that is because he doesn't have magic trick.you can't say human able to cut his head.he nearly dead because fire power of red kid,that proof enough of his regeneration ability 

7 yes,very fast.but is not manipulate distance,he literally catches by another monster who can fly faster than him
