I have a questions about indemnitor(cosigners) on a bail bond?

can a indemnitor(cosigner) sue another cosigner over a contract dispute? what had happen was that i was dumb for cosigner for a defendant that i don't even know and i didn't read the paper saying im responsible and the defendant's girlfriend who i know had ask me to do a favor for her in which she Promise me 150 dollars in return and i did and after that the bail bond company had start calling all the cosigners and i didn't pick up the phone because i was focusing on school so defendant girlfriend who is one of the cosigner had made a payment to bail bonds and didn't really tell me about it and before that her and other two cosigners who i really didn't know had came with a low amount payments like 50 dollars and bail bonds didn't accept it so basically i wasn't aware of any other this for 4 or 5 months until when i got a call from bail bonds through voice mail messages stating that bail bonds haven't received money from the defendant or cosigners who are liable for the payment in case the defendant didn't make payments so i start answer the call and try to see what i can do and i got in contact with one of the cosigner the gf and she tell me some excuses so i realize that im responsible for four other people in regards to make payments when we should help each other in coming up with the payments and they are not stepping up to help me make payments but i am and the gf of the defendant told me i cant sue since i signed and took responsibility but can i sue the other cosigners as to get my money back from them
