every time i turn on my car it sequels its loud and annoying and can last from 5 secs to 30 plus and when I turn on the ac It also does it and at 5k or 6k rpm to redline I think it might be a pulley but im not sure does anyone know what it might be maybe the belt?

Sequel (noun): 1.A published, broadcast, or recorded work that continues the story or develops the theme of an earlier one.
2.Something that takes place after or as a result of an earlier event.

Oh..SQUEAL...I get it now.

Simple - check for loose belts. if tight, remove and clean belts and pulleys. reinstall/tighten to correct deflection.

^yup
Squeal- belts loose
Squeak- pulleys

By your description, I'm sure your have loose belts.
My car had a squeaking noise for like 5-10 minutes during warm up, I did my 120k and replaced my tensioner and idler pulleys and it went away.

also if you have aluminum ud pulleys they tend to squeal after a whiles use as the belt polishes the pulleys grooves.

If it isn't the belts being too loose it could also be the idler pulleys themselves, the bearings go bad after a while

Clean?!? REPLACE the belts, they can wear in a way that will not show to the untrained eye.
