when i enter new grf some of my grfs have a triangle next to them and says its disabled how do i enable?

That has to do with the grfs themselves. If they don't give any error except for being disabled, well, you have to guess the cause. It could be that it's not climate compatible, not compatible with other sets, or some other causes...
If you click a grf, it will most likely show it's error somewhere at the bottom of the screen.

Some grfs have dependencies that must be loaded first.
