if someone has been charged with aggravated battery and its there first time charge can they get out of jail and just co have a fine or probation what

It depends on the nature of your case.  If you beat up a pregnant lady, you're much less likely to get away with just probation and a fine than if you committed an aggravated battery based upon the victim standing in a publlic location.  You really should be trying to avoid a felony, not trying to avoid jail.
