Possibility of transferring data over the same-level networks, rather than the higher-level network

This all depends on how these networks are connected. If there is no direct BGP connection between A and B, this would never work. Your assumptions on what 'peering' and 'transit' are, are a bit off I ...

Possibility of transferring data over the same-level networks, rather than the higher-level network

Technically it's definitely possible, it all depends on B's configuration. How they route traffic between locations and whether they permit transit traffic is totally up to them.

Connecting L3 and L2 switches with VLAN settings

If you need to connect devices on both L2 switches to either VLAN then you need to trunk those VLANs (on both the L3 and the L2 switch). Since you seem to be using a management subnet 192.168.0.0/24 ...

Make printer in different subnet accessible to other subnet

You are not using subnets, it's all the same flat 192.168.10.0/24 network. The L3 switch just works as an L2 switch. Correct the PCs subnet masks to /24 and you're done. If you create VLANs with ...
