Need to know if i can have more than 24GB virtual memory be distributed among 3 virtual machines from 24GB physical memory on the host.
For example, i have a host with 24GB physical memory
Then can i have the following
1st VM 18GB
2nd VM 8GB
3rd VM 8GB

You can overcommit memory, and it's a common practice.
The thing is what will happen if all the VMs start needing all memory resources at the same time. (Balloning/Swapping)
Other than that, you would be fine.
It's possible to do memory-overcommitting for your VMs, but remember it can reduce the overall performance of the ESXi host and its virtual machines because, in confronting lack of memory resources, they (VMs) just using their swap files. If you didn't provide a physical disk with higher IOPS (like the SSD) as the swap space, many problems in the operation of virtual machines will be observed.
Which VMware product?
ESXi 6.5
