How will IP addresses be allocated on a given network?

Question

Computer networks

If everything is clear with networks 1,2,3, this is
192.168.1.0/25
192.168.1.128/26
192.168.1.192/28
Then network 5 goes through the switch of network 4, does this somehow affect the distribution of addresses?

2) How to change the addressing in the network if changes in the
topology are proposed according to the figure

Answer 1

That network 5 goes through the switch of network 4, does this somehow affect the distribution of addresses?

No
No

Answer 2

may or may not affect, depends on the particular case and what and how you configure on the equipment.
The classic model in Figure 1 is all computers 4, 5 in the same address space, separated by vlan (not necessarily separated, depending on needs)
A special case of the first figure is managed switches and each switch has its own address space.
The classical model in Figure 2 - all computers 4.5 in their address space (i.e. 4, 5 subnets do not have intersections)
A special case - bonding is configured on the interfaces leading to switches 3 and 4 and there is the same virtual ip , respectively, it leads to one address space.
Most likely, you will have a classic model, and then in the second figure you need to split the network behind the last switches into 2 different subnets, and specify the gateway (router interface) that they need on the computers in these subnets.
