Cluster setup

i have to create a cluster.

i am shooting my questions here…
1). How many worker nodes can handled by t3.medium master node?
2). How pods can be created inside t3.small worker node ?
3). if i create t3.small instance as worker node and pods inside it , how containers can be created in each pod.?
4). can we create master in minikube and create worker node in aws ec2 , can we combine this both and create a cluster?
5). is this any formula to calculate cluster setup and master and worker node?
