Can I manually add address?

[baimurzin]

Is it possible to add manually peers before starting ipfs daemon
And how I can get value from second machine to add it on first machine?

And for example I have run a daemon in local network on several devices, and then I give access to global network would files accessible to others people. If yes, how can I prevent it?

Use the Bootstrap list to add peers before starting in the configuration.

And how I can get value from second machine to add it on first machine?

Use ipfs id to find the second machine's peer addresses.

network would files accessible to others people. If yes, how can I prevent it?

Files are accessible to other people as soon as a node bootstraps to one of the default nodes or finds a node which is connected to the outside.

If yes, how can I prevent it?

Enable private networks. See #3397 (comment)
