Designing VLANS and subnetting (FOR SCHOOL PROJECT)

I could use some help with a few of the VLANs I need to design. I need to subnet a class C network -192.168.234.0/24 I just need to figure out how to get Number of Hosts, CIDR, and IP address for two VLANS: First -8 computers and two printers Second -3 servers with 3 NICs each

Even some resources that would help me learn to solve this would be amazing
