Hi, My topology is:

Main Gateway(192.168.1.1)—RB333))(((RB411—RB433

“—” is Lan Cable, “)))(((” is Wireless Bridge.

My problem is I cannot get ip from 192.168.1.1, My RB333 can get ip from 192.168.1.1 but my RB411 and RB433 can’t get. How can I do that?

You don’t need DHCP-relay if you have bridge.
Probably it would be easier to create bridge in the entire network, RB433 is directly reachable by Main Gateway over Ethernet network.

How?

Use ‘bridge’

Be careful when you need to bridge wireless, because wireless station doesn’t support bridging, WDS is good solution for these cases,
