 * Well Oliver is voiced voiced by a 13 young old
 * Fukase has been in his group since 2007 so at least a decade nd began his career while he and the original two others were in highschool. So Fukase is in his mid 20s.
 * Asami Shimoda is currently 30 year old. She first started with Vocaloid 9 years ago so was roughly 20/21.

I'd put Fukase as more closer in age to VY2 and Piko then Oliver. So about I'd age him about 16-20, rather then 12-15.

Len isn't a true reflection of a 14 year old boy, never was, so its difficult to judge him. Though he is 14 years old, his vocalrepreents a deep tones young female, its the same with Rin only she reflects the higher ranges and Len the lower of Asami Shimoda's vocal. Basically, Rin is a "head voice" and Len is a "chest voice". In truth Len and Rin represent the 18-24 age range. Fukase is currently 30 (according to Google), but I think he started recording the vbs like a few years ago or something. VY2 and Piko's vps are probably in their mid-20s by now, but when they first recorded their voicebanks they were in their early 20s. (Well VY2's vp could also have been in his teens because all we know is that "he was younger than Piko")
