I'm newbie with OSPF and routing, can you explain, what I doing wrong, that I cann't see
anything OSPF routes from R5?
Here is link that I used
router ospf 32
network 10.1.3.0 0.0.0.255 area 23
network 10.1.23.0 0.0.0.255 area 23
network 10.1.35.0 0.0.0.255 area 35
network 10.10.10.0 0.0.0.255 area 23
A router can't be an OSPF ABR without the presence of area 0.
To correct your situation, you can assign the loopback in R3 in area 0 or create a virtual link between R3 and R2.
But I have ABR router R2 that is configured to backbone 0.
Maybe I didn't understand some thing right?
DId I configured network equal to this link
By definition, an ABR is a routing participating in multiple OSPF areas.
R3 is participating in multiple OSPF areas but it's lacking area 0.
Until Area 0 is configured locally in R3, the router won't be able to route between areas.
Without changing much your current network topology, the easiest way is to assign loopback0 to area 0.
The link you've presented has the middle router participating on a single non-backbone area - it isn't an ABR and that's allowed.
Your design, the middle router (R3) is participating in multiple non-backbone areas. If you want your design to be similar as the link, you need to make R3 member of area 23 or area 35 in all its links and change either R2 or R5 accordingly.

But what about this link, is it right in configuration?
Here Router R2 doesn't have neighbors on area 0 too.
