..."I make more peers, steel have ONLY 1 connection."...

variants:
1) peers have a wrong wallet config
config must contain this options:

rpcuser=...
rpcpassword=...
server=1
daemon=1
rpcallowip=127.0.0.1
rpcport=...
port=...
txindex=1
listen=1

2) peers dont have a delicated external ip address   
3) access to peers wallet closed by firewall
4) bugs in wallet code(unlikely)

variants:
1) wrong wallet config
2) coins is a very fragmented.
