ID needed

[CGY_Betta_Guy]

After starting my cycle a few weeks ago I have been slowly been finding lots of little creatures that I have no clue what they are... can anyone help me ID them so I can research them? Also if anyone notices anything in the pics that would be cause for concern please let me know since I am a newbie and still learning.

1) Unidentified growth which is slowly getting longer. The purple portion in center of shot that is in focus.


2) Looking down into my Edge tank I saw these growing... looks good but no idea what it might be


3) this appears to be a red coraline algae but I havent tried to scratch it yet to confirm.. just wanted to make sure its not the bad red slime


4) some clammy looking thing sticking outta my rock. The picture is out of focus as I had to shoot at an angle



5) Hair algae or a soft coral?


6) wormy looking dude with a head that moves when light shines on it.
