well today i went to my friends house and everyone was like jamming to songs.

I know i can play scales and jam with them but i need some scales or pentatonic that would allow me to do it well

any help?

learn the 5 possitions of the pentatonic.
blues scale
the modes.
natural harmonic

you can go on and on. the pentatonic will do just fine though, and make sure to not stray out of it a bit. just play around with it, play what sounds good, and if it doesnt sound good slide back or forth till you catch a good note, your ear should tell you if you hit a sour note or not.
