Nagato might be older. Think about it.
Jiraiya was like in his late 20's when he met Nagato, who was like 13.
He left and they grew into their late teens while mid 30 year old Jiraiya met Minato in his mid-teens (14ish).
Minato had to be at least 20ish when he had Naruto, and Nagato had to be in his late 20's - mid 30's.
*Jiraiya had to be in his late 30's (38) by the time Minato had Naruto
*Part 1, Naruto's 12ish and Jiraiya would be like 50
Naruto's 16 now and Minato's would be in his mid-late 30's while Nagato's in his late 30's to early 40's.
*Jiraiya had to be 52ish at that time
*Nagato's about 5 years older than Minato.
*Jiraiya was about 10 years older than the Ame Orphans when they met.
