Currently relay nodes are not 'low-power' in the mesh specification because they have the radio listening 100%. You can lower this to trade off battery for packet latency if you don't need <20ms delays.
It takes ~7 seconds for a node to reboot, initialize, and re-sync keys with the network. This is assuming that the previous keys&state were stored in flash. (optional feature in the nRF Mesh SDK) If you don't save network state, then provisioner will have to add them 1 at a time, after they have initialized. ~2 seconds per node.
```
100 nodes with Persistant storage:      7 seconds  
100 nodes without Persistant storage: 4 minutes
```

I doubt you ever power down all the relay nodes (why???); they go to sleep mode if nothing else is "happening", but since they relay messages the radio is on most of the time, and that more or less answers your question 1: it is most likely more than 5mA you are looking at for those relay nodes.

for example, a computer with Widows10 power on and reset, maybe they need 10 or 20 second time for start widows, I mean, How much time for 100 relay node configure or start after power on or reset?

How close is "all closed"? With 100 nodes it's highly unlikely they are "all close" to within 1 room? Maybe across 2 floor is what you have in mind?
